the closet distance between earth and Mars is approximately 3.39x10^7 miles. the fastest rocket leaving earth travels at an average speed of approximately 3.6x10^4 miles per hour. at this rate what expression could be used to determine the approximate number of hours it would take the rocker to travel from earth to mars

The expression that could be used to determine the approximate number of hours it would take the rocket to travel from Earth to Mars is:

\( \frac{3.39 \times 10^7\text{ miles}}{3.6 \times 10^4\text{ miles per hour}} \)
