Question 377560: A pipe can fill a swimming pool in 10 hours. If a second pipe is opened, the two pipes together can fill the pool in 4 hours. How long would it take the second pipe alone to fill the pool? -Thanks a lot! Answer by edjones(8007) (Show Source):
You can put this solution on YOUR website! Let x = number of hour it take the 2nd pipe alone to fill the pool.
1/10 + 1/x = 1/4
2x+20=5x Multiply each side by 20x
3x=20
x=20/3 hrs.
