The closest distance between Earth and Mars Is approximately 3.39 × 10^7
miles.
The fastest rocket leaving Earth travels at an average speed of approximately 3.6 × 10^4 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? _
B. How many hours would it take to travel from Earth to Mars? _
A. The expression that can be used is: \( \frac{3.39 \times 10^7}{3.6 \times 10^4} \)
B. Calculating this expression gives us:
\( \frac{3.39 \times 10^7}{3.6 \times 10^4} = \frac{3.39}{3.6} \times 10^{7-4} = 0.9425 \times 10^3 = 942.5 \) hours.
Therefore, it would take approximately 942.5 hours for the rocket to travel from Earth to Mars at that speed.
