two trains leave the station at the same time one heading west and the other East the westbound train travels at 55 miles per hour East bound train travels at 75 miles an hour how long will it take for the two trains to be 338 miles apart

Answers

recall your d = rt, distance = rate * time

so... one train goes west and the goes the opposite way... alrite... so... notice, by the time 338 miles have been covered by both, it will have been "t" hours, and whatever "t" is, is the same amount of time the westbound train has been running as well as the eastbound train has been running.

now, let's say, since by "t" hours they've covered 338 altogether, so, if the westbound train has covered say "d" miles, then the eastbound train would have covered the slack from 338 and d, that is, "338 - d".

[tex]\bf \begin{array}{lccclll} &\stackrel{miles}{distance}&\stackrel{mph}{rate}&\stackrel{hours}{time}\\ &------&------&------\\ Westbound&d&55&t\\ Eastbound&338-d&75&t \end{array} \\\\\\ \begin{cases} \boxed{d}=55t\\ 338-d=75t\\ ----------\\ 338-\boxed{55t}=75t \end{cases} \\\\\\ 338=75t+55t\implies 338=130t\implies \cfrac{338}{130}=t\implies \stackrel{hours}{2.6}=t[/tex]

so, 2hours and 36 minutes.

the distance from the earth to the Sun is approximately 9.3×10^7 miles. if light travels 1.2×10^7 miles in 1 minute, how many minutes does it take the light from the sun to reach the earth ?

Answers

t takes 5 1/3 minutes for light from the sun to reach earth. The Moon is closer to earth, so it,s light reaches earth faster about 5 19/60 minutes faster than from the sun. How long does light from the moon take to reach earth.

Final answer:

It takes approximately 12.47 minutes for light from the Sun to reach the Earth.

Explanation:

To find out how many minutes it takes for light from the Sun to reach the Earth, we can divide the distance from the Earth to the Sun by the distance light travels in 1 minute.

First, let's convert the distance from miles to kilometers. 1 mile is approximately 1.60934 kilometers, so the distance from the Earth to the Sun is approximately 1.496 × 108 kilometers.

Now, we divide this distance by the distance light travels in 1 minute: 1.496 × 108 kilometers / 1.2 × 107 kilometers per minute = 12.47 minutes.

Therefore, it takes approximately 12.47 minutes for light from the Sun to reach the Earth.

Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

2*x^2-3*x-(2)=0

Step by step solution :Step 1 :Equation at the end of step 1 : (2x2 - 3x) - 2 = 0 Step 2 :Trying to factor by splitting the middle term

The middle term is,  -3x  its coefficient is  -3 .
The last term, "the constant", is  -2

Step-1 : Multiply the coefficient of the first term by the constant   2 • -2 = -4

Step-2 : Find two factors of  -4  whose sum equals the coefficient of the middle term, which is   -3 .

The depth finder on a fishing boat gives readings that are within 5% of the actual water depth. when the depth finder reading is 250 feet, the actual water depth x lies within a range given by an inequality.

Answers

A range refers to the least and greatest amount with respect of a certain number. In this case, the number referred to is the actual water depth, denoted as x. The general equation would be:

Depth finder reading = Actual Water Depth +/- 0.05*Actual Water Depth
250 ft = x +/- 0.05x
250 ft = x(1 +/- 0.05)
x = 250/(1 +/- 0.05)

Solving the equation:
x = 250(1 + 0.05) = 262.5 ft
x = 250(1 - 0.05) = 237.5 ft

Hence, the actual depth is between the range 262.5 ft - 237.5 ft.

Suppose the length of a diagonal of a square increases from 16 cm to 16.1 cm. What would the change in the area of the square be

Answers

The change in area will be such that it will increase by 1.605 or 1.25%.

What is a square?

A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.

Area of square = Side²

The perimeter of the square = 4× side

The area of a square with diagonal x is given as x²/2.

Area with diagonal 16 cm ⇒ 16²/2 = 128 cm²
Area with diagonal 16.1 cm ⇒ 16.1²/2 = 129.605 cm²

Change of area = 129.605 - 128 = 1.605 cm².

Percentage change = 1.605/128 x 100 = 1.25%.

Hence "The change in area will be such that it will increase by 1.605 or 1.25%".

The shanghai maglev train is one of the fastest trains in the world, traveling about 2144 miles in 8 hours. How many miles does it travel in one hour? The distance between columbus ohio and new york city is about 560 miles.how many hours would it take the train to travel between the cities

Answers

2144miles ÷ 8hrs = 268miles in 1hrs

trip 560 miles ÷ 268 miles per hours = 2hrs and 8min

Answer:

The train travels 268 miles in 1 hour. It would take 2.0896 hours to travel between the cities.

Step-by-step explanation:

Consider the provided information.

The shanghai maglev traveling about 2144 miles in 8 hours.

This can be written as:

2144 miles = 8 hours

Divide both sides by 8.

2144/8 miles = 8/8 hours

268 miles = 1 hours

Thus, the train travels 268 miles in 1 hour.

The distance between Columbus Ohio and new York city is about 560 miles. We need to find how many hours would it take the train to travel between the cities.

268 miles = 1 hours

Divide both the sides by 268.

1 miles = 1/268 hours

Now multiply both sides by 560.

560 miles = 560/268 hours

560 miles = 2.0896 hours

Hence, it would take 2.0896 hours to travel between the cities.
