Question

Marco bicycles 20 miles in 2 = hours.2 1 / 1What is his average rate in miles perhour?

Answer 1

Marco's bicycle speed rate: 20 miles in 2 1/2 hour

To get the average speed or rate, we use the following formula:

`\text{Speed = }\frac{total\text{ distance}}{\text{total time }}`

Using the formula, we get:

`\text{speed = }\frac{total\text{ distance}}{\text{total time}}=\frac{20\text{ miles}}{2.5\text{ hr}}=\frac{8\text{ miles}}{1hr}=8mi.\text{ per hour}`

Therefore, the average rate of Marco when doing bicycle is 8 miles per hour.
