A container in the shape of a cuboid has a square base of side x and a height of (10-x). It is given that x varies with time, t, where t 0. The container decreases in volume at a rate which is inversely proportional to t.
When t = 1/10, x = 1/2 and the rate of decrease of x is 20/37.

Question

A container in the shape of a cuboid has a square base of side x and a height of (10-x). It is given that x varies with time, t, where t > 0. The container decreases in volume at a rate which is inversely proportional to t.
When t = 1/10, x = 1/2 and the rate of decrease of x is 20/37.
