Problem

A swimmer heads straight across a

250\,\text{m}

‐wide river at

1.8\,\text{m/s}

relative to the water. The river flows east at

0.90\,\text{m/s}

. Assuming the swimmer maintains the same heading throughout, calculate how long it takes to reach the opposite bank and how far downstream from the starting point the swimmer lands.
