Question

A boat is headed with a velocity of 18 meters/second toward the west with respect to the water in a river. If the river is flowing with a velocity of 2.5

meters/second in the same direction as the boat. What would be the magnitude of the boat's velocity?
A.
16.5 meters/second
B.
20.5 meters/second
c.
18 meters/second
D.
2 meters/second
E.
45 meters/second

Answer 1

B

Step-by-step explanation:

The boat's velocity relative to the earth = the boat's velocity relative to the river + the river's velocity relative to the earth

v = 18 m/s + 2.5 m/s

v = 20.5 m/s
