Question

In 3 minutes, a conveyor belt moves 400 lbs of recyclable aluminum from the delivery truck to a storage area. A smaller belt moves the same quantity of cans the same distance in 4 minutes. If both belts are used, find how long it takes to move the cans to the storage area. I think it is 3 1/2 minutes but I'm not sure. Please help!

Been a while since I addressed this type of rate problem.
