FInd the circumference of the tire:
C = 2 x PI x r
C = 2 x 3.14 x 14
C = 87.92 inches.
For every revolution of the tire it travels 87.92 inches.
In one minutes the car travels 87.92 x 120 = 10,550.4 inches.
In 5 minutes the car travels 10550.4 x 5 = 52,752 inches.
52,752 / 12 = 4,396 feet
1 mile = 5280 feet
4396 / 5280 = 0.833 miles
I calculated 3 different measurements. Use the one needed.
