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.
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. At that rate, the expression used to determine the approximate number of hours it would take the rocket to travel from Earth to Mars is:
\( \frac{3.39 \times 10^7}{3.6 \times 10^4} \)
B. Calculating the expression:
\( \frac{3.39 \times 10^7}{3.6 \times 10^4} = \frac{3.39}{3.6} \times 10^{7-4} \)
\( \frac{3.39}{3.6} = 0.9425 \)
Therefore, it would take approximately 0.9425 x 10^3 hours to travel from Earth to Mars.
This is equivalent to 942.5 hours.
