A motorcycle tire with a radius of 16 inches rotates at a rate of 150 revolutions per minute (rpm). a) Find the linear speed of the tire in inches per minute.
b) Find the angular speed of the tire in radians per minute.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
