a boat travels north across a river at a velocity of 22 meters/second with respect to the water. the rivers velocity is 2.2 meters/second to the east. what is the resultant velocity of the boat as measured from the land

Question

anonymous · Answer

I think you should start by drawing out your scenario. Then draw your velocities as vectors from point to point. Then we can use the formula:
$$\huge v_{boat/water}=v_{boat}-v_{water}$$You're given the velocity of the boat with respect to the water and the velocity of the water of the river; now just calculate the velocity of the boat. Both the velocity of the boat and the water are with respect to the indicated reference point that is considered "stationary," which is the land.
