Box L is 4 times as heavy as Box M. Box N is 7.29 kg heavier than Box M. The total mass of Box L and Box M is 46 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
= 4 x 1 u
= 4 u
Mass of Box N = 1 u + 7.29
Total mass of Box L and Box M
= 1 u + 4 u
= 5 u
5 u = 46
1 u = 46 ÷ 5 = 9.2
Mass of Box M
= 1 u
= 9.2 kg
(b)
Mass of Box N
= 1 u + 7.29
= 9.2 + 7.29
= 16.49 kg
Answer(s): (a) 9.2 kg; (b) 16.49 kg
