Box L is 3 times as heavy as Box M. Box N is 7.59 kg heavier than Box M. The total mass of Box L and Box M is 58 kg.
- What is the mass of Box M?
- What is the mass of Box N?
(a)
Mass of Box M = 1 u
Mass of Box L
= 3 x 1 u
= 3 u
Mass of Box N = 1 u + 7.59
Total mass of Box L and Box M
= 1 u + 3 u
= 4 u
4 u = 58
1 u = 58 ÷ 4 = 14.5
Mass of Box M
= 1 u
= 14.5 kg
(b)
Mass of Box N
= 1 u + 7.59
= 14.5 + 7.59
= 22.09 kg
Answer(s): (a) 14.5 kg; (b) 22.09 kg
