Question 14
Work on your own.
A spacecraft is on a mission to Mars from Earth (Figure 8.8). It travels the first half of the distance at an average speed of 20 000 km/h. After a gravitational boost, it travels the second half at an average speed of 30 000 km/h. The total distance from Earth to Mars at the closest approach is approximately 54.6 million km.
The spacecraft returns to Earth following the same speed pattern. What is the total time for the round trip?
