Question

A person needs to fill 18 water jugs with a hose. Filling the first 3 jugs has taken 5 minutes. How long to finish filling the remaining jugs?

Answer 1

10.8 minutes

Explanation:

Given data

We are told that the number of Jugs is 18

Filling the first 3 jugs has taken 5 minutes

let us find the filling rate

Rate= 3/5

Rate= 0.6 Jugs per minute

Hence the rate of filling is 0.6 Jugs per minute

Therefore the time take to fill the remaining 16 jugs is

TIme= Rate*Number of Jugs

TIme= 0.6*18

Time= 10.8 minutes
