Question

Deandre drove 715 miles in 13 hours.
At the same rate, how long would it take him to drive 605 miles?

Answer 1

Answer:

11

Step-by-step explanation:

first divide 715 and 13, which is 55

then you divide 605 and 55, which is 11

so he drove 605 miles in 11 hours.

Answer 2

Answer:

The time it would take Deandre to drive 605 miles is 11 hours.

Step-by-step explanation:

The problem is related to speed, distance and time.

Speed (or rate) of an object is the measure of how rapidly the object moves form point A to point B.

It is computed by dividing the distance traveled by the time taken to travel this distance. That is,

$Speed=\frac{distance}{time}$

It is provided that Deandre drove $distance=715 miles$ in $time=13 hours$.

Then the speed at which Deandre was driving can be computed as follows:

$Spped=\frac{distance}{time}\\ =\frac{715}{13}\\ =55$

Thus, Deandre's speed was 55 miles/hour.

Now, if Deandre needs to drive 605 miles at the same speed, i.e 55 miles/hour, then the time taken will be,

$Speed=\frac{distance}{time}\\time=\frac{distance}{speed}\\=\frac{605}{55}\\ =11$

Thus, the time taken by Deandre to drive 605 miles at the speed 55 miles/hour is, 11 hours.
