Question

The International Space Station orbits Earth about every 90 minutes. About 40% of the time, Earth prevents the space station from receiving direct sunlight. About how many minutes per orbit does the space station not receive sunlight?

Short answer

The minutes per orbit, the space station did not receive sunlight about 36 minutes.

Step-by-step solution

Step 1. Given Information.

Earth prevents the space station from direct sunlight about 40% of 90 minutes.

Step 2. Calculation.

International space station orbits Earth about every 90 minutes.

Earth prevents the space station from direct sunlight about (in percent) 40%.

Earth prevents the space station from direct sunlight about (in number) is

$\begin{array}{l}=40\%of90\\ =\frac{40}{100}\cdot 90\left[writepercentasawholenumber\right]\\ =36\end{array}$

Step 3. Conclusion.

The minutes per orbit, the space station did not receive sunlight about 36 minutes.
