A cyclist travels 45 miles in 3 hours. What is the cyclist's speed?

Hint: Use the formula: d = r x t (distance = rate x time)

Remember that division and multiplication are INVERSE operations. So, 45 = r x 3

so you will have to divide the distance by the time to get the rate.

45 ÷ 3 to find the rate

A: 15 miles per hour

B: 12 miles per hour

C: 16 miles per hour
