I know the answer is 2.5 but i want to know if there are other methods other than what I used...

Answer 4

in first two mins 1/3 of the tub will be filled
so, remaining 2/3
and in one min 4/15 of the tub will be filled by the two pipes together
so in 5/2 mins the remaining portion that is 2/3 of the tub will be filled by these two pipes together
