Math reading problem, Fraction conversion.

Question

In 2 minutes, a conveyor belt moves 300 pounds of recyclable aluminum from the delivery truck to a storage area. A smaller belt moves the same quantity of cans the same distance in

22 minutes. If both belts are​ used, find how long it takes to move the cans to the storage area.

I'm trying to figure out how to convert this into fraction form as well.

Answer 1

They both take the same time amount of time to do the job separately, so they will take half the time (11 minutes) to do the job together.

Each does 1/22 of the job in a minute, so together they do 1/22 + 1/22 = 1/11 of the job in a minute, so it will take them 11 minutes to do the job together.
