Two taps can together fill a tank in 9 3/8hrs. The tap of larger diameter takes 10 hours less than the smaller one to fill the tank separately. Find the time in which each tap can separately fill the tank.
I know that the equation is
1/x-10 + 1/x =8/75
but how do u get it as 1/x. Why and how? Pls explain thanks.

1/(x-10)+1/x=8/75
multiply both side of the equation (x-10)(x)

anonymous · Answer

then the equation     x+(x-10)=8/75(x)(x-10)
