Question

Solve the problem. The formula d = rt gives the distance traveled in time t at rate r. If a bicyclist rides for 2.3 hours and travels 41 miles, what was her average speed ?

Question options:

a: 38.7 miles per hour

b: 5.6 miles per hour

c: 17.83 miles per hour

d: 9.43 miles per hour

Answer 1

17.83

Explanation:

d = r*t

d = 41 miles

t = 2.3 hours

r = ??

d = rt Substitute

41 = r * 2.3 Divide by 2.3

41 / 2.3 = r Switch sides

r = 41/2.3

r = 17.83 mph Answer
