A young sumo wrestler decided to go on a special diet to gain weight rapidly. He gained weight at a constant rate. The table compares the wrestler's weight (in kilograms) and the time since he started his diet (in months).

How fast did the wrestler gain weight?

___ kilograms per month

Finding the rate of the weight gain, we divide the total weight gained with the total number of months that took to gain that weight.

Total time (months) = 0.5 + 2 + 3.5 = 6 months

Total weight (kg) = 80.6 + 88.4 + 96.2 = 265.2 kilograms

Rate = Kg ÷ Months

Rate = 265.2 ÷ 6 = 44.2

44.2 kilograms per month
