Question

A barrel had 20 liters of water. Water leaked out from the barrel at a constant rate. After 24 hours, 14 liters of water was left in the tank. How many liters of water leaked out per hour?

Answer 1

the barrel had 20 liters....after 24 hrs, it had 14 liters......that means in 24 hrs, it leaked (20 - 14) = 6 liters....so it is leaking 6 liters every 24 hrs

liters / hr = 6/24 = 0.25.....so it is leaking 0.25 (or 1/4) liters per hr
