Question

An astronaut weighs 49 kg on earth. On the moon, an

object's weight is 1/6 of its weight on earth. On Mars, an
object's weight is 0.38 of its weight on earth. What is the
difference between the astronaut's weight on Mars and her
weight on the moon? Round your answer to the nearest
tenth. *

approximately 10.4 kg

approximately 1.4 kg
approximately 104 kg

approximately 49 kg​

Answer 1

The correct answer is A. Approximately 10.4 kg.

Explanation:

1. Let's review the information given to us for solving the question:

Weight of the astronaut on Earth = 49 kg

Weight of the astronaut on the moon = 1/6 * 49 kg

Weight of the astronaut on Mars = 0.38 * 49 kg

2. What is the difference between the astronaut's weight on Mars and her weight on the moon? Round your answer to the nearest tenth.

Weight of the astronaut on the moon = 1/6 * 49 kg

Weight of the astronaut on the moon = 8.2 kg

Weight of the astronaut on Mars = 0.38 * 49 kg

Weight of the astronaut on Mars = 18.6 kg

Difference between the astronaut's weight on Mars and her weight on the moon = 18.6 - 8.2

Difference between the astronaut's weight on Mars and her weight on the moon = 10.4 kg
