Question

Rachel drove 715 miles in 13 hours.

At the same rate, how long would it take her to drive 275 miles?

Answer 1

We can use the formula for speed, distance, and time:

speed = distance ÷ time

to find Rachel's rate of driving. We can then use this rate to calculate how long it would take her to drive 275 miles.

Rachel's rate of driving is:

speed = distance ÷ time = 715 miles ÷ 13 hours = 55 miles per hour

To find how long it would take Rachel to drive 275 miles at this rate, we can rearrange the formula as follows:

time = distance ÷ speed = 275 miles ÷ 55 miles per hour = 5 hours

Therefore, it would take Rachel 5 hours to drive 275 miles at the same rate

Answer 2

5 hours

Explanation:

To find out how long it would take Rachel to drive 275 miles at the same rate, we can use proportionality. We can set up a ratio of the distance she drove to the time it took her to drive that distance:

715 miles / 13 hours = 275 miles / x

where x is the amount of time it would take Rachel to drive 275 miles.

To solve for x, we can cross-multiply and simplify:

715 * x = 13 * 275

715 * x = 3575

x = 3575 / 715 = 5

Therefore, it would take Rachel 5 hours to drive 275 miles at the same rate.
