A farmer knows that the time, t, taken by goats to eat all the grass in a particular field is inversely proportional to the number of goats, g, in the field.

When there are 25 goats in the field, the time taken to eat all the grass is 36 days.

You may assume that all the goats eat grass at the same rate.

Find a formula for the time, t, in terms of the number of goats, g.

Hence, find the time taken for all of the grass to be eaten when there are 20 goats in the

field.

The farmer needs the grass to last for at least 40 days.

What is the greatest number of goats that should be allowed in the field?
