A leaking tank's water level (in litres) is plotted as a line graph: 0 min 100, 10 min 80, 20 min 60. If the leak continues at the same rate, after how many minutes from the start will the tank be empty?

Question

Accepted Answer

50. The level falls 20 L every 10 min, i.e. 2 L per minute. From 100 L, time to empty = 100/2 = 50 minutes.
