The tire on Frank's bike moves 75 inches in every rotation. How many rotations will the tire make after Frank rides 50 feet?



Answer :

The foot is subdivided into 12 inches ;
50 × 12 ÷ 75 = 600 ÷ 75 = 8 rotations ;

Set up a proportion:

First convert 75 inches to feet.

75 in = 6.25 ft

1/6.25 = x/50

Multiply 50 to both sides:

50 * 1/6.25 = x

50/6.25 = x

x = 8

So the tire will rotate 8 times after Frank rides 50 feet.
