. Two pipes running together can fill up a cistern in 3(1/3) minutes. If one pipe takes 3 minutes more than the other to fill the cistern, find the time in which each pipe would fill the cistern. [Ans: 8 min]
But I'm getting an irrational number,
what I did
let time of first pipe be x and time for second pipe be x-3
so the equation is
1/x + 1/(x-3) = 1
x^2 -5x + 3 = 0
from ehre it is clear taht an irrational root is obtained.....
