The water in a river moves south at 10 mi/hr. a motorboat travels due east at a speed of 20 mi/hr relative to the shore. determine the speed and direction of the boat relative to the moving water.

22.36 mi/hr

Step-by-step explanation:

Given

water in a river moves south at

motorboat travels due to east at a speed of

Velocity of boat relative to the moving water

Magnitude of

with the x axis.

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
