Tanks X and Y contain 500 and 200 gallons of water respectively. Water is being pumped out of tank X at a rate of K gallons per minute and water is being added at M gallons per minute. How much time will elapse before the two tanks contain equal amounts of water?

1) 5/(M+K) hours
2) 6*(M+K) hours
3) 300/(M+K) hours
4) 300/(M-K) hours
5) 60/(M-K) hours

Here is the equation

500 - K*T = 200 + M*T

T * (M+K) = 300

T = 300/ (M+K)

so T= 300/(M+K)*60 = 5/M+K

This part of the question "water is being added to M gallons per minute" has typo. Please correct it. Thanks.
