Textbook Question

Chapter 8.4, Problem 85PE

Joe rides a bicycle and his wheels revolve at 80 revolutions per minute (rpm). Therefore, the total number of revolutions, r, is given by r ( t ) = 80 t , where t is the time in minutes. For each revolution of the wheels of the bike, he travels approximately 7 ft. Therefore, the total distance he travels D ( r ) (in feet) depends on the total number of revolutions, r, according to the function D ( r ) = 7 r .

a. Find ( D ∘ r ) ( t ) and interpret its meaning in the context of this problem.

b. Find Joe’s total distance in feet after 10 min.
