Box X is 4 times as heavy as Box Y. Box Z is 5.93 kg heavier than Box Y. The total mass of Box X and Box Y is 48 kg.
- What is the mass of Box Y?
- What is the mass of Box Z?
(a)
Mass of Box Y = 1 u
Mass of Box X
= 4 x 1 u
= 4 u
Mass of Box Z = 1 u + 5.93
Total mass of Box X and Box Y
= 1 u + 4 u
= 5 u
5 u = 48
1 u = 48 ÷ 5 = 9.6
Mass of Box Y
= 1 u
= 9.6 kg
(b)
Mass of Box Z
= 1 u + 5.93
= 9.6 + 5.93
= 15.53 kg
Answer(s): (a) 9.6 kg; (b) 15.53 kg
