Approximate number of hours = (closest distance between Earth and Mars) / (average speed of rocket leaving Earth)
Therefore, the expression that could be used is:
3.39 x 10^7 miles / (3.6 x 10^4 miles per hour)
If the closest distance between Earth and Mars is approximately 3.39 times 10^7 miles and the fastest rocket leaving Earth travels at an average speed of approximately 3.6^4 miles per hour.
A. At that rate, which expression could be used to determine the approximate number of hours it would take the rocket to travel from Earth to Mars?
