Question

You plan to drive 240 miles in 6 hours. If your friend wants to drive

300 miles, how many miles per hour faster would your friend have
to drive to get there at the same time as you?

Answer 1

Your friend needs to drive 10 miles per hour faster to cover 300 miles in the same time it takes you to drive 240 miles, which is 6 hours.

Step-by-step explanation:

To solve the problem, we first need to determine your average speed for the 240 miles trip in 6 hours. This can be found using the formula:

Vavg = distance ÷ time

For your trip, Vavg = 240 miles ÷ 6 hours = 40 mph.

Now, since your friend needs to drive 300 miles in the same amount of time (6 hours), we need to find the speed your friend must travel at:

Your friend's speed = 300 miles ÷ 6 hours = 50 mph.

To find out how much faster your friend needs to drive, we subtract your speed from your friend's speed:

50 mph - 40 mph = 10 mph faster

Therefore, your friend needs to drive 10 miles per hour faster to cover 300 miles in the same time it takes you to drive 240 miles.
