The closest distance between Earth and Mars is approximately 3.39 x 107 miles.

The fastest rocket leaving Earth travels at an average speed of approximately 3.6 × 104 miles per hour.
(8 points)
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? (3.39 × 107) (3.6 × 104)
B. How many hours would it take to travel from Earth to Mars? 12,204

A. 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:

(3.39 × 10^7) / (3.6 × 10^4)

B. Calculating this expression:
(3.39 × 10^7) / (3.6 × 10^4) = 9429.16667 hours

Therefore, it would take approximately 9429.16667 hours for the rocket to travel from Earth to Mars at that speed.
