Question at position 3
If she has traveled 240 miles, how many hours has she been driving?

Answer 1

To solve this problem, we can set up a proportion.

Let x represent the number of hours Rachel has been driving.
According to the problem, the distance she has traveled (240 miles) is directly proportional to the number of hours she has been driving (x hours).

So, we can write the proportion as:

100 miles/2.5 hours = 240 miles/x hours

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

100x = 2.5 * 240
100x = 600
x = 600/100
x = 6

Therefore, Rachel has been driving for 6 hours.

Answer 2

The distance Rachel has driven varies directly with how many hours she has been driving. After 2.5 hours, she has traveled 100 miles.
