Question 1009257: Brad and tom can mow their yard together with two lawn mowers in 30 min. when brad work alone it takes him 50 min. how long would it take tom by himself? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Call Tom's time, x. Then the set up is
30/50 + 30/x = 1
Now multiply by 50x and we get
30x + 1500 = 50x
1500 = 20x
x = 75 minutes
