Question

A swimmer swims across a river at a velocity of 0.8 m/s in a direction perpendicular to the river banks. The water flows down the river at 0.6 m/s. Find the results and velocity of the swimmer.

Answer 1

Below

Step-by-step explanation:

The two speeds form the legs of a right triangle ....the resultant is the hypotenuse ...use Pythagorean theorem :

r^2 = .8^2 + .6^2

r^2 = 1

r = 1 m/s
