Real boat situation.

To cross a river of width b=320 mb = 320 \text{ m}, a captain steers his boat always aiming towards a point that is directly across the river from his starting point. The velocity of his boat relative to river current is vbr=2.5 m/sv_{br} = 2.5 \text{ m/s} and river current velocity is vr=1.5 m/sv_{r} = 1.5 \text{ m/s} everywhere.

Determine the time tt (in seconds) the boat will take to cross the river.
