Question

A tap fills an eighty litre tank in 5 minutes. What is the rate of flow of water with respect to

time, in litres per second?

Answer 1

0.27 lt/s

Explanation:

80 liters in 5 minutes

5 minutes are 300 seconds (5x60)

We know how many seconds we need to fill up the tank (300 seconds for 80 liters). Now we need to know how many liters we can fill up in 1 second, as the question requires "liters per second".

80 lt / 300 sec

X lt / 1 sec

80 x 1

---------- = X

300

X = 0.2666666...

X = 0.27 lt / s
