Question 1171883
n a stretch of interstate, a vehicle's tires rotate at a rate of 840 revolutions per minute. The diameter of each tire is 26 inches. Find the following rounding to the nearest tenth if necessary.

12 inches = 1 foot
5280 feet = 1 mile
60 minutes = 1 hour
Convert the linear speed of the tires to miles per hour.?
  {{{(pi*26*840*60)/(5280*12)}}} = 65 mph
Find the linear speed of the tires in inches per minute.?
  {{{pi*26*840}}} = 68,612.4 inches/min
Find the angular speed of the tires in radians per minute?
  {{{840*360*(pi/180)}}} = 5278 radians/min
