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 (V_{p}) = 6ms^{-1}

The velocity of the river (V_{r}) = 8ms^{-1}

To find:

The velocity of a person with respect to the river (V_{pr)} =?

Formula used:

V_{pr }= V_{p} - V_{r}

Solution:

V_{pr } = 6ms^{-1} - 8ms^{-1}

V_{pr} = 2ms^{-1}

Answer:

The velocity of a person with respect to the river is 2ms^{-1}
