Question

when Jamie's car moves forward such that each tire makes one full rotation,the car has traveled 72 inches. how many full rotations will the tires need to make for Jamie's car to travel 10 yards?

Answer 1

The answer is 5 full rotations. 72/2 = 36in
36 inches in a yard
1 rotation = 2 yards
10/2 = 5
answer = 5

Answer 2

The tire need to make 5 rotations.

Explanation:

Given,

The distance travelled in one rotation = 72 inches,

⇒ The number of rotation the car travelled for 72 inches = 1

⇒ The number of rotation the car travelled for 1 inches =
`(1)/(72)`

Also, the car travelled 10 yards,

Since, 1 yards = 36 inches,

Thus, the distance travelled by the car = 36 × 10 = 360 inches,

Hence, the number of rotation the car travelled for 360 inches

`=(360)/(72)` = 5
