A space shuttle orbits earth one time in 90 minutes how many times does it orbit earth in six hours

4 times

Step-by-step explanation:

We know that 6 hours is 360 minutes. If we know that the space shuttle orbits once every 90 minutes, we divide 360 minutes (Total amount of time) by 90 minutes (the time that it takes for the shuttle to orbit once), to find the amount of times it orbits in the 6 hour time frame.

360 divided by 90 is 4.

So the shuttle orbits earth 4 times in 6 hours.

60 minutes=1 hour

360 minutes=6 hours

so 360 minutes/90 minutes

so your answer is 4 hours
