Answer 1

Answer:

hii

your answer is here !

Step-by-step explanation:

If 7 pipes can fill 3 tanks in 45 minutes,

then they can fill 1 tank in 15 minutes.

This means that one pipe can fill one tank in 15*7 = 105 minutes.

Five pipes can fill one tank in 105/5 = 21 minutes.

If you have more tanks to fill, just multiply the number of tanks by 21 minutes.
