A cable car travels by clamping onto a steel cable that circulates in a channel beneath the streets. The cable is driven by a large 20-foot-diameter pulley, called a sheave. The sheave turns at a rate of 19 revolutions per minute. Find the speed of the cable car, in miles per hour, by determining the linear velocity of the cable (rounded to the nearest hundredth of a mile).
