Assume that the distance from Earth to the moon is exactly 238,855 miles and that it took astronauts 75 hours to reach the moon in 1969. How far did the astronauts travel each hour, on average, during their trip to the moon?

Question

3,004.73 miles
3,184.7 ModifyingAbove 3 with bar miles
3,317.4305 miles
3,817.430 ModifyingAbove 5 with bar miles

Answer 1

To find the average distance traveled by the astronauts each hour during their trip to the Moon, we can use the formula:

\[ \text{Average speed} = \frac{\text{Total distance}}{\text{Total time}} \]

Given:

• Total distance = 238,855 miles
• Total time = 75 hours

Now we can calculate the average speed:

\[ \text{Average speed} = \frac{238,855 \text{ miles}}{75 \text{ hours}} \approx 3,181.0667 \text{ miles per hour} \]

Rounding this to two decimal places gives us approximately 3,181.07 miles per hour. Since none of the provided options exactly match this calculated average speed, the closest correct answer based on rounding and representation is:

3,184.7 \(\overline{3}\) miles (if interpreting the bar properly).

Therefore, based on the provided choices, the average speed at which the astronauts traveled is likely intended to be this option.
