The weight of an object on Mars varies directly as its weight on Earth. A person who weighs 95 kg on Earth weighs 38 kg on Mars. How much would a 100 kg person weigh on Mars?
36.1 kg
40 kg
38 kg
41 kg
The weight of an object on Mars is directly proportional to its weight on Earth, so we can set up a proportion:
95 kg (Earth) = 38 kg (Mars)
100 kg (Earth) = x (Mars)
Using cross-multiplication, we get:
95 * x = 100 * 38
x = (100 * 38) / 95
x = 3800 / 95
x = 40
Therefore, a 100 kg person would weigh 40 kg on Mars.
Therefore, the correct answer is: 40 kg
