Answer:
The time taken to get the shuttle is 6.91 minutes.
Explanation:
Given that.
Mass of an astronaut, 
Distance between astronaut and shuttle, d = 48.1 m
Mass of the camera, 
Speed of camera, v = 12 m/s
We need to find the time taken by the astronaut to reach her shuttle. Both shuttle and astronaut are at rest, their initial velocities will be equal to 0. Using the conservation of linear momentum as :

The time taken to get the shuttle is given by :

or
t = 6.91 minutes
So, the time taken to get the shuttle is 6.91 minutes.
