Question

NEED HELP QUICK!!!!Charmaine is riding her bike. The distance she travels varies directly with the number of revolutions (turns) her wheels make. See the graph below.

(a) How many revolutions does Charmaine make per foot of distance traveled?
(b) What is the slope of the graph?

Answer 1

Explanation:

Circumference of the wheel = (pi)d = 45*3.14 = 141.3 inches

Distance traveled in inches: 5*141.3 = 706.5 inches
