Algebra Level 3

Suppose you have a grassy field, and cows eat grass at a constant rate. Keep in mind, the grass keeps growing continuously.

48 cows can clear all the grass off the field in 90 days.

120 cows can clear all the grass off the field in 30 days.

How many cows would be needed to clear all of the grass in 16 days? Round up to the nearest whole cow.
