B. How many hours would it take to travel from Earth to Mars? Response area

Hours: 942 12,204 106 210

Answer 1

To find the answers to the provided questions:

A. The expression to determine the approximate number of hours it would take the rocket to travel from Earth to Mars can be formulated by dividing the distance by the speed. Therefore, the expression would be:

\[ \frac{3.39 \times 10^7 \text{ miles}}{3.6 \times 10^4 \text{ miles per hour}} \]

B. To calculate how many hours it would take to travel from Earth to Mars, we can proceed with the mathematical computation:

1. Convert the scientific notation:

   • Distance: \(3.39 \times 10^7 = 33,900,000\) miles
   • Speed: \(3.6 \times 10^4 = 36,000\) miles per hour

2. Divide distance by speed: \[ \text{Hours} = \frac{33,900,000 \text{ miles}}{36,000 \text{ miles per hour}} \approx 942.5 \text{ hours} \]

Rounding this can lead us to choose 942 hours.

Thus, the responses would be:

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

B: 942 hours
