Answer:
Revolution = 127.24 revolutions
Step-by-step explanation:
<em><u>Circumference of the tire = πD</u></em>
Where D = 15 inch
So,
C = 15π = 47.1 inch
<u><em>In feets:</em></u>
47.1 inch = 3.93 feet.
So, <u>one revolution = 3.93 feet</u>
<u><em>Travelling 500 feet will make the following revolutions:</em></u>
Revolution = 500 feet/3.93 feet
Revolution = 127.24 revolutions
