Question

An astronaut is returning to Earth in a spacecraft. if the spacecraft is descending at a rate of 13.8 kilometers per minute, its change in height after 5 1/2 minutes will be

Answer 1

To find the change in height after 5 1/2 minutes, we can use the formula:

\[
\text{Change in height} = \text{rate} \times \text{time}
\]

Given:
- Rate = 13.8 kilometers/minute
- Time = 5.5 minutes

Now, substituting the values into the formula:

\[
\text{Change in height} = 13.8 \, \text{km/min} \times 5.5 \, \text{min}
\]

Calculating that:

\[
13.8 \times 5.5 = 75.9 \, \text{km}
\]

Therefore, the change in height after 5 1/2 minutes will be **75.9 kilometers**.
