Answer 2

Answer:

25 hrs

Step-by-step explanation:

Rate of Flow of water = 120litres/minute.

Volume of cubodial tanker = 180 meter cube

1 meter cube = 1000litres.

Therefore,180 meter cube = 180 × 1000 = 180000litres.

Time taken to fill the water tank

= 180000 × 1/120minutes

= 180000/120 minutes

= 1500 minutes

= 1500/60hrs

= 25hrs.
