Using the slope concept, it is found that the angle of the swimmer's resultant vector is of 71.83º.
<h3>What is a slope?</h3>- The slope is given by the <u>vertical change divided by the horizontal change.</u>
- It's also the tangent of the <u>angle of depression.</u>
In this problem:
- The person swims 6.4 meters per second north, hence the vertical change is of 6.4.
- The person is being pushed by a current moving west at 2.1 meters per second, hence the horizontal change is 2.1.
Then, considering that the slope is the tangent of the angle of depression , which is also the angle of the swimmer's resultant vector, we have that:
Using a trigonometric calculator:
The angle of the swimmer's resultant vector is of 71.83º.

If it takes the cold water faucet x minutes to fill 1 tub, then its flow rate is (1 tub)/(x min).
The hot water faucet takes 4 times as long, so its flow rate is (1 tub)/(4x min).
Together, the total flow rate is (1 tub)/(3 min), so we have
