edit: woops I messed up the title. It should have been relative to the shore.
1. The problem statement, all variables and given/known data
A boat’s speed in still water is 1.95 . The boat is to travel directly across a river whose current has speed 1.10 . Determine the speed of the boat with respect to the shore

2. Relevant equations
I'm not sure.

3. The attempt at a solution
I thought it would be a sqauared plus b squared is equal to c squared. a being the speed of the boat in still water, b being the current and c being the speed with respect to the shore. This however does not give the right answer

When it says 'directly across', I think it means the boat is to finish directly across from where it started. How is that to be achieved?

boat crossing river

The boat have to steer at an angle in order go right across the river.
