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? A. 9.43 miles per hour B. 5.6 miles per hour C. 17.83 miles per hour D. 38.7 miles per hour

Answer 1

C. 17.83 miles per hour
Instead of using D=R*T use D/T=R
D=41
T=2.3
41/2.3=17.83

Answer 2

C.) 17.83 because if d=rt and d= 41 and t= 2.3, then the rate or speed is 17.83
