Answer:
The car's tire moves at a speed of 1002.24 feet per minute.
Step-by-step explanation:
Given:
The radius of the car tire is r = 16 inches
Since 12 inches equals 1 foot,
16 inches converts to
×16 = 1.33 feet
The wheel completes 120 revolutions every minute.
Let the speed of the tire be s feet per minute.
The wheel's circumference is calculated as 2 ×
× radius.
Here,
equals 3.14.
Thus, circumference = 2 × 3.14 × 1.33.
Therefore, Circumference = 8.352 feet.
Now, Speed = circumference of the wheel × revolutions per minute.
Thus, Speed = 8.352 feet × 120 revolutions per minute.
∴ Speed = 1002.24 feet per minute.
Thus, the car's tire speed is 1002.24 feet per minute. Answer
