The child at 5 years old would weight: 60 lb (27.16 kg) If he continues gaining weight a that rate
To solve this problem we will use a rule of three with the problem information:
3 years-------- 36 lb child's weight
5 years -------- x
Applying the rule of three we get:
x = ( 5 years * 36 lb child's weigh) / 3 years
x = 60 lb
By converting the weight units from lb to kg we have:
x = 60 lb * 16.3 kg/36 lb
x = 27.16 kg
