Physics help please?

A 92-kg astronaut and a 2000-kg satellite are at rest relative to a space station. The astronaut pushes on the satellite, giving it a speed of 0.14 m/s directly away from the station. Seven and a half seconds later the astronaut comes into contact with the station. What was the initial distance from the station to the astronaut?

    first, what is his velocity, using conservation of momentum.

    2000•0.14 = 92V

    V = 3.04 m/s

    3.04 m/s x 7.5 s = 22.8 m
