What is the speed of a housefly in feet per second round to the nearest hundredth

The speed of the housefly miles per hour is equals to:

=> In every 1 mile = 5280 feet

=> 4.4 miles = 23 232 feet

=> now let’s convert the hour to seconds

=> In 1 hour = 3 600 seconds

Thus:

=> 23 232 / 3600

=> 6.4533333 ... repeating decimals.

Then it says in the problem ti round off to the nearest hundredths

=> 6.45 feet / seconds - The speed of the housefly in feet per seconds
