Tim drove 4 hours at an average speed of 60 miles per hour. How many hours would it take Tim to drive the same distance at an average speed of 50 miles per hour?

4.8 hours

Step-by-step explanation:

Distance = speed * time

If Tim drove 4 hours at 60 miles per hour

Than he drove a total of 4*60 miles

He drove 240 miles

Time = distance : speed

If he drove 240 miles at 50 miles per hour

Than he took 240:50 hours

He took 4.8 hours (4 hours and 48 minutes)
