Answer:

11

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:

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

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=(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=(distance)/(time)\\ =(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=(distance)/(time)\\time=(distance)/(speed)\\=(605)/(55)\\ =11

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