It takes the first pipe 9 more hours to fill the pool than the first and the second pipes together and 7 less hours than it woul
Vikki [24]
Let the time taken for the first pipe to fill the pool be x hours
time taken for second pipe to fill the pool is (x+7) hours
time taken for both pipes to fill the pull =(x-9) hours
thus fraction of time taken for both will be written as:
1/(x-9)
thus total fraction for pipe 1 and 2 will be
1/x+1/(x+7)=1/(x-9)
solving for x we get:
x=-3 or x=21
but time is positive, then time taken  by first pipe is 21 hours
time taken by both pipes will be 21-9=12 hours
