Aspace shuttle orbits earth one time in 90 minutes. how many times does orbit earth in six hours?

90 minutes =1.5 hours=one orbit
Divide 6 by 1.5 because this will help you see how many orbits can be made in 6 hours (since 1.5 hours=1 orbit)
6/1.5=4
Therefore the space shuttle orbits around the Earth 4 times in 6 hours.
Hope this helps!

1. isolate the variable, in this case, d. subtract 35.5 on both sides of the equation.2. 52 subtracted by 35.5 is 16.53. therefore your answer would be d= 16.5this is the basics of pre algebra, isolating variable through adding, subtracting, multiplying, and dividing, if you have any other questions to ask just comment!
