The relation between time and water pulled by a water pump is direct. If a pump raises 600 liters water in 45 minutes, how much water it will raise in one hour?
- 800 liters
- 7 liters
- 500 liters
- None of these
Explanation
Given the direct relation between time and water pulled:
Let's find the rate of water pulled per minute:
600 liters / 45 minutes = 40/3 liters per minute
In one hour (60 minutes):
Water pulled = (40/3) * 60
= 40 * 20
= 800 liters
