Heather drove
715
miles in
13
hours.
At the same rate, how long would it take her to drive
495
miles?
Confused...
Are you sure the equation say 13 hours and not 3 hours? I found the exact equation online but with 3 hours not 13. I can try to help either way though :D
715/13 = 55 mph
495/55 = 9 hours
oh, looks like Ms. Sue has got you covered. xD
@ronald It's 13
To find out how long it would take Heather to drive 495 miles at the same rate, we can use the concept of speed.
To calculate speed, we divide the distance traveled by the time taken. In this case, speed = distance / time.
First, let's find the rate at which Heather was driving. We can calculate the rate by dividing the distance she covered (715 miles) by the time taken (13 hours).
So, her rate of driving is 715 miles / 13 hours = 55 miles per hour (mph).
Now that we know Heather's driving rate, we can determine how long it would take her to drive 495 miles. To find the time, we divide the distance (495 miles) by the rate (55 mph).
So, the time it would take her to drive 495 miles is 495 miles / 55 mph = 9 hours.
Therefore, it would take her approximately 9 hours to drive 495 miles at the same rate.
