I should have gotten 108m/s Can yoou show me the correct way to solve this problem? Thanks so much for your time and effort. I really would apprecitate it!

Momentum:

80(253)=(6090-80)delta v

deltav=?

This is an approximation. A better solution is to take the average mass of the spacecraft as (6090-80/4), but it wont matter much.

There is an exact method in Calculus, but I assume you are not a calculus person.
