A tap can fill ,2/5th of a tank in 8 minutes,
a. how much of the tank will be filled in 20 minutes?
b. how much time will it take to fill the whole tank?​

Answer 1

Answer:

a) In 1 minute it would fill (2/5) / 8 i.e 0.05 of the tank.

    In 20 minutes => 20 x 0.05 = 1 = 5/5 of the tank will be filled

b) Let time = t

    t x 0.05 = 5/5

     t = 1 / 0.05 = 20 minutes
