Question

When diving, a hummingbird can reach a speed of 40 miles per hour. What is this speed in ft per second? Round to the nearest hundredth if necessary

Answer 1

Answer:

Step-by-step explanation:

Given that when  diving, a hummingbird can reach a speed of 40 miles per hour.

i.e. speed of humming bird = 40 miles per hour

We have $1 mile = 5280 feet\\40 miles = 5280(40) = 211200 feet$

In one hour = 211200 feet

We have $1 hour = 3600 seconds$

Hence speed in ft/sec = $\frac{211200}{3600} =58.67$ ft/sec

Answer 2

1 mile = 5280 ft.....so 40 miles = (5280 * 40) = 211200 ft
60 seconds per minute, and 60 minutes per hr....so 1 hr = (60 x 60) = 3600 seconds.

211,200 / 3600 = 58.67 ft per second
