One boat tows another boat by means of a tow line, which is under a constant tension of 495 N. The boats move at a constant speed of 4.75 m/s. How much work is done by the tension in 1.10 min?
Not sure how to apply the work-energy theorem. I assume velocity needs to be calculated from given speed and change in distance.

You do not have to calculate velocity. They tell you what it is.
Work = (towing force) x (distance)
Distance = 4.75 m/s * 66 seconds = 313.5 m
Put it all together
Work = (towing force) x (distance)
Distance = 4.75 m/s * 66 seconds = 313.5 m
