Question

Joe and Moe can mow the lawn in 33 minutes if they work together. If Moe works twice as fast as Joe, how long does it take Joe to mow the lawn alone?

Answer 1

x = the time it takes Joe to mow the lawn alone
2x = the time it takes Moe to mow the lawn alone

x + 2x = 33
3x = 33
x = 11

Answer: 11 Minutes
