Question

6 The tire on Frank's bike moves inches in

75 in
one rotation. How many rotations will the tire
have made after Frank rides 50 feet?
(Lesson 10.4)
(A) 2
(B) 8
C 12
D 24

Answer 1

If one rotation moves 75 inches, you can find that one rotation moves 6.25 feet by dividing 75 by 12 since 12 inches are in one foot. 75/12= 6.25 feet.
Then you can divide 50 by 6.25 to find the number of rotations needed to travel 50 feet which if done correctly should equal 8 rotations. 50/6.25=8 rotations

The answer is B
