-----------------------------------------------------
one pipe fills four times faster as the other.
-----------------------------------------------------

Either "One pipe fills four times as fast as the other." or "One pipe fills at four times the rate of the other".

p, the time for the slow pipe alone to fill THE TANK.
slow pipe, 1%2Fp
fast pipe, 4%2Fp
pipes together, 1%2F84

1%2Fp%2B4%2Fp=1%2F84
