The closest distance between Earth and Mars is approximately 3.39×10^7

Question

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? _____

Answer 1

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.
