1. A man points his rowboat north from A to B, straight across a river of width 100 m. The river flows due east. The man starts across, rowing steadily at 0.75 m/s and reaches the other side of the river at point C, 150 m downstream from his starting point.(adsbygoogle = window.adsbygoogle || []).push({});

What is the speed of the river?

2. Pythagorean Theorem: a^2 + b^2 = c^2

3. 100^2 + 150^2 =

10000 + 22500 = 32500

square rt of 32500 = 180.277

after this I wasn't sure about what to do, please help!
