Calculate Tire Angles for 2ft Diameter & 60,000 Miles

[assirma]

1. A set of new tires have a diameter of 2.0 ft and are warranted for 60,000 miles. What is the angle through which one of the tires will rotate during the warranty period?



2. covert diameter in ft to meters and find the radius: .6096 x .5= .3048
convert miles to meters: 9.65 x 10^7



3. angle= s/r (9.65 x 10^7/.3048)

Is this way off?

Hi assirma,

Your approach looks right to me.
