Answer:
Hummingbird can reach a speed of 58.67 ft/sec.
Explanation:
Consider the provided information.
A hummingbird can reach a speed of 40 miles per hour.
This can be written as:
40 miles = 1 hour
40 miles = 3600 second
40/3600 miles = 1 second .....(1)
Hummingbird can reach a speed of 2/3 miles per second.
As we know 1 mile = 5280 feet
Multiply both side by 40/3600
40/3600 miles = 5280 × 40/3600 feet
40/3600 miles = 58.67 feet .......(2)
From 1 and 2 we can concluded.
58.67 feet = 1 second
Hence, hummingbird can reach a speed of 58.67 ft/sec.
