Question

A hummingbird can travel up to 15 meters per second.

What is the hummingbird's speed in miles per hour?

1 mile ≈ 1609 meters.

Enter your answer as a decimal to the nearest tenth.

Answer 1

You need to use conversion factors. First change meters to miles and then seconds to hours



`15 (meter)/(sec)`

`15 (meter)/(sec) * (1 \space mile)/(1609 meters) =`

`(15\space miles)/(1609) = (9.32 miles)/(sec)`


`(9.32 miles)/(sec) * (60sec)/(1hour) = (559.2 miles)/(hour)`
