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