Question
The velocity of a person on the boat is 6m/s, and the velocity of the river is 8m/s.
Find the velocity of the person with respect to the river.
- 2
- 3
- 1
- 4
Hint:
2 m/s
The correct answer is: 2
Given:
The velocity of a person on a boat (Vp) = 6ms-1
The velocity of the river (Vr) = 8ms-1
To find:
The velocity of a person with respect to the river (Vpr) =?
Formula used:
Vpr = Vp - Vr
Solution:
Vpr = 6ms-1 - 8ms-1
Vpr = 2ms-1
Answer:
The velocity of a person with respect to the river is 2ms-1
