When diving a humming bird can reach a speed of 40 miles per hour. what is this speed in feet per second? round to the nearest hundreth if necssary

There are 5280 feet in a mile so multiply that by 40 (5280 * 40 = 211,200)

Divide that by the amount of minutes in an hour (211,200 : 60 = 3,520)

Divide that by the amount of seconds in a minute (3,520 : 60 = 58.66)

Your answer is 58.66. I don't think it would be necessary to round to the nearest hundred.
