for the first drain the equation you need would be: 2n = 108

for drain B your equation would be: 5n = 108

these are your equations because a number times the amount of water the drain drains per minute will equal 108

to solve use inverse operations and divide 108 by the amount of water the drain drains in one minutes 

Drain A- 108/2 = 54
it takes 54 minutes for drain a to empty a pool with 108 gallons of water

Drain B- 108/5 = 21.6
it takes 21.6 minutes for drain b to empty a pool with 108 gallons of water in it
