Box F is 4 times as heavy as Box G. Box H is 5.86 kg heavier than Box G. The total mass of Box F and Box G is 78 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 + 5.86
Total mass of Box F and Box G
= 1 u + 4 u
= 5 u
5 u = 78
1 u = 78 ÷ 5 = 15.6
Mass of Box G
= 1 u
= 15.6 kg
(b)
Mass of Box H
= 1 u + 5.86
= 15.6 + 5.86
= 21.46 kg
Answer(s): (a) 15.6 kg; (b) 21.46 kg
