Question

A person needs to fill 15 water jugs with a hose. Filling the first 3 jugs has taken 4 minutes. How long to finish filling the remaining jugs?

​

Answer 1

20 minutes

Explanation:

Rate x Time = jobs

The rate is 3 jugs/ 4 minutes.

The number of jobs is 15

Use T for time

3/4T = 15 Multiply both sides by 4/3 to get the variable T by itself

(4/3) 3/4 T = 15(4/3)

T = 20 minutes

Answer 2

9 minutes i think
3 divided by 4 = 0.75
0.75 times 12(remaining jugs) = 9 :)
hope this helps!
