Question

1. At takeoff, a rocket has a mass of 2.3 million kilograms. After using enough fuel to reach a height

of 61 kilometers, its mass is 0.131 million kilograms. How much fuel does the rocket use to reach
a height of 61 kilometers?

Answer 1

The rocket uses 2.169 million kilograms of fuel to reach a height of 61 kilometers, calculated by subtracting the final mass from the initial mass of the rocket.

Step-by-step explanation:

To calculate the amount of fuel a rocket uses to reach a height of 61 kilometers, you subtract the mass of the rocket after using the fuel from the mass of the rocket at takeoff. The initial mass is 2.3 million kilograms, and after reaching 61 kilometers, the mass is 0.131 million kilograms.

The amount of fuel used can be found through the following calculation:

Initial mass - Final mass = Mass of fuel used

2.3 million kg - 0.131 million kg = 2.169 million kg

Therefore, the rocket uses 2.169 million kilograms of fuel to reach a height of 61 kilometers.
