Given that, the driver increased the speed of the car by 10% for the next hour of the trip,  distance traveled in 1 hour at the increased speed is 82.5 miles.

How far did the car travel in the last hour?

Given the data in the question;

  • Initial distance traveled = 240 mile
  • Time taken = 3.4 hours
  • Initial Speed = ?
  • Increased speed = ?
  • Distance traveled at the increased speed = ?

First we calculate the initial speed of the car.

Initial Speed = Distance/Time

Initial Speed = 240 mi / 3.2 hours

Initial Speed = 75 mi/hr

If the Initial speed is increased by 10%

Increased speed = Initial speed × ( 100 + 10 )%

Increased speed = Initial speed × 110%

Increased speed = 75 mi/hr × 110%

Increased speed = 82.5 mi/hr

Now, distance traveled in 1 hour at the increased speed will be;

Distance = Increased speed × Time

Distance = 82.5 mi/hr × 1hr

Distance = 82.5 mi.hr/hr

Distance = 82.5 miles

Given that, the driver increased the speed of the car by 10% for the next hour of the trip,  distance traveled in 1 hour at the increased speed is 82.5 miles.
