Box V is 4 times as heavy as Box W. Box X is 5.67 kg heavier than Box W. The total mass of Box V and Box W is 57 kg.
- What is the mass of Box W?
- What is the mass of Box X?
(a)
Mass of Box W = 1 u
Mass of Box V
= 4 x 1 u
= 4 u
Mass of Box X = 1 u + 5.67
Total mass of Box V and Box W
= 1 u + 4 u
= 5 u
5 u = 57
1 u = 57 ÷ 5 = 11.4
Mass of Box W
= 1 u
= 11.4 kg
(b)
Mass of Box X
= 1 u + 5.67
= 11.4 + 5.67
= 17.07 kg
Answer(s): (a) 11.4 kg; (b) 17.07 kg
