Answer:

180.07 rev / min

Step-by-step explanation:

Diameter (D) of each wheel =28 inches

Circumference (C) =  π x 28 = 28π inches

Conversions:

1 mile = 63,360 inches

1 hour = 60 min

Hence 15 miles / hour

= (15)(63,360) inches / hour

= (15)(63,360) / 60  inches / min

= 15,840 inches per min

Number of revolutions per min = Number of inches per min ÷ circumference in inches

=15,840 inches/min ÷ 28π inches

= 180.07 revolutions per min
