Answer :

John's mass is approximately 253.53 pounds, while Sally's mass is given as 115 pounds. Therefore, John is the heavier of the two.

To compare the masses of John and Sally, we need to make sure both masses are in the same unit. John's mass is given in kilograms (kg), and Sally's mass is given in pounds (lb). To compare them, we can convert one of them to the other unit.

Since 1 kilogram is approximately equal to 2.20462 pounds, we can convert John's mass from kilograms to pounds:

John's mass (in pounds) = 115 kg * 2.20462 lb/kg ≈ 253.53 lb

So, John's mass is approximately 253.53 pounds.

Now that both John and Sally's masses are in pounds, we can compare them.

John's mass is approximately 253.53 pounds, while Sally's mass is given as 115 pounds. Therefore, John is the heavier of the two.
