Question

Assume the

28 Water is being poured into a fish tank at a rate of 2 L every 10 seconds. The tank is 1.2 m long by Im
wide by 80 cm high. How long will it take to fill the tank? Give the answer in minutes.

Answer 1

80 minutes

Explanation:

1. Determine the volume of the tank

volume = length x width x height

100 cm = 1 meter

80cm /100 = 0.8m

1.2 x 1 x 0.8 = 0.96m³

2. convert litre to meter

1 liter = 0.001 m

2 litres = 0.002m

3. determine the time it would take to fill 0.96m

(0.96x 10) / 0.002 = 4800 seconds

4. convert seconds to minutes

60 seconds = 1 minute

4800 seconds / 60 = 80 minutes

2l = 0.0
