#### Answer

a.) 1056 second
b.) 17.6 minutes

#### Work Step by Step

Given, Tropical cockroaches are the fastest land insects. They can run about 5 feet per second.
To find how long it would take the cockroach to travel one mile, First we need to find the how many seconds it will take to travel one mile.
As we know 1 mile = 5280 feet, so divide 5280 with 5.
5280/5 = 1056 second
Therefore Tropical cockroaches will take 1056 second to travel one mile.
b.) We need to calculate the time in minutes i.e. 1056 sec= min
You are converting from a smaller unit to a larger unit (a second is smaller than a minute) so divide.
Because 1 min = 60 seconds, divide by 60
1056/60 = 176/10 = 17.6 min
Therefore Tropical cockroaches will take 17.6 minutes to travel one mile.
