Question 866658
The radius of the tires on an off-road pickup truck 21 inches. The truck's tires are turning at the rate of 220 revolutions per minute. Given that 1 mile is 5280 feet, determine the speed of the truck in miles per hour.
***
{{{220(rev/min)*2(pi)21(inches/rev)* (ft/12inches)*60(min/hr)*(mile/5280 ft)=220*2(pi)21*60/(12*5280)=27.49(miles/hr)}}}
