Question

a hummingbird can travel up to 15 meters per second. what is the hummingbirds speed in miles per hour? 1 mile ≈ 1609 meters enter your answer, as a decimal to the nearest tenth, in the box. mph

Explanation:

Step1: Convert meters to miles

We know 1 mile $\approx$ 1609 meters. So 15 meters $=\frac{15}{1609}$ miles.

Step2: Convert seconds to hours

There are 3600 seconds in 1 hour. Since the speed is currently in miles per second, to get miles per hour, we multiply the speed in miles per - second by 3600. The speed $v$ in miles per hour is $v=\frac{15}{1609}\times3600$.
Calculate $\frac{15\times3600}{1609}=\frac{54000}{1609}\approx33.6$.

Answer:

33.6
