Box F is 4 times as heavy as Box G. Box H is 5.62 kg heavier than Box G. The total mass of Box F and Box G is 69 kg.
- What is the mass of Box G?
- What is the mass of Box H?
(a)
Mass of Box G = 1 u
Mass of Box F
= 4 x 1 u
= 4 u
Mass of Box H = 1 u + 5.62
Total mass of Box F and Box G
= 1 u + 4 u
= 5 u
5 u = 69
1 u = 69 ÷ 5 = 13.8
Mass of Box G
= 1 u
= 13.8 kg
(b)
Mass of Box H
= 1 u + 5.62
= 13.8 + 5.62
= 19.42 kg
Answer(s): (a) 13.8 kg; (b) 19.42 kg
