Answer:
c.) 2000
Step-by-step explanation:
In 2 minutes, the motorcycle travels a distance of ...
(6300 ft/min)(2 min) = 12600 ft
The circumference of the tire is ...
C = 2πr = 2π(1 ft) = 2π ft
The distance traveled is n times the circumference, where n is the number of revolutions of the tire.
12600 = 2π·n
12600/(2π) = n = 6300/π ≈ 2005.4
The tire makes about 2000 revolutions in 2 minutes.
