I'm doing a basic analysis of the trip to the Moon.

I've estimated the speed as follows:

distance:       363,104,000 m
time:           4 days, 6 hours, 45 minutes =  369,900 s

average speed:  363,104,000 m / 369,900 s   ~ 982 m/s

How much fuel was used to decelerate the CSML at the moon.

1. How much fuel was used to decelerate the CSML at the moon.
2. How well does this speed estimate compare to the actual velocity of the CSML as it approached the Moon?
