Question

The International Space Station takes 644 minutes to orbit Earth 7 times. About how long does each orbit take?

Answer 1

`92` minutes

Explanation:

`(644" minutes")/(7" orbits") = 1xx(644" minutes")/(7" orbits")`

`= (1/7)/(1/7)xx(644" minutes")/(7" orbits")`

`= (644/7" minutes")/(7/7" orbits")`

`=(92" minutes")/(1" orbit")`
