Your car travels 600 miles in 6 hours. You stop the car for lunch for 1 hour and then you continue on your trip for another 14 miles and finish the entire trip in 8 hours. What was your car's average speed while you were driving?

Average speed = 87.71 Miles/hour

Explanation:

The section of my journey while driving is divided ino two.

First section.

Distance covered = 600 miles

Time taken = 6 hours

Velocity or speed = distance/time

Speed = 600/6

Speed = 100 Miles/hour

Section two.

Distance traveled = 14 miles

Time taken = one hour (because total time is 8 hours, first section is 6 hours, I spent one hour eating lunch, so it's remaining one hour for the 14 miles)

Speed = 14/1

Speed = 14 miles/hour

But average speed is total distance divided by total time taken.

Avg speed = 614 miles/7 hours

Avg speed = 87.71 Miles/hour
