Answer 1

What is the formula for work?

Answer 2

Work = Force x Distance,
where we consider only the component of force in the direction of motion. Here the force and the direction are parallel, so we can say
Work = Force x Distance
and not worry about that technicality.

Now, you know the amount of Work and the Force. Hence you can solve for Distance.
