Question

Two identical taps can fill a bathtub in 15 minutes. Calculate the time taken for 3 such taps to fill the same bathtub.

Answer 1

lets take the that 2 tap volume is x then 1 tap volume is x by 2 because 2 tap fill the whole bathtub in 15 minutes then 1 if we give it 15 minutes to fill the bathtub it will it it half then so it will it full in 30 minutes as 15 x 2 is 30 and if we put 3 taps we will divide it by the minute taken by 1 tapto fill the bathtub means we will divide 3 by 30 so we will get the answer 10 three tap will fill the whole bathtub in ten minutes .I am rani from 5 class
