A boat’s speed in still water is 1.95m/s . The boat is to travel directly across a river whose current has speed 1.20m/s .
Determine the speed of the boat with respect to the shore.

Despite, I did it like taking the sqrt (1.95^2+1.20^2)

is there something wrong I did?

Thank you for your care.

    respect to the shore?

    The boat has to head upstream, and that velocity is countered by the stream:


    So the slant angle reduces the speed across.

    Oh yes, u r right, didn' t care it, ty so much
