1. A boat, whose speed in still water is 2.20m/s, must cross a 260m wide river and arrive at a point 110m upstream from where it starts. To do so, the pilot must head the boat at a 45 degree upstream angle. What's the speed of the river's current?(adsbygoogle = window.adsbygoogle || []).push({});

2. How do you incoporate 45 degrees into the work?

3. So far, I have

a^2+b^2=c^2

c= sqrt(110^2+260^2)=282m
