Ariver current has a velocity of 5 km/h relative to the shore. a boat moves in the same direction as the current at 4 km/h relative to the river. how do you calculate the velocity of the boat relative to the shore?

subtract the boat’s velocity from the river’s velocity

add the river’s velocity to the boat’s velocity

divide the river’s velocity by the boat’s velocity

Add the river’s velocity to the boat’s velocity

Explanation:

It is given that,

A river current has a velocity of 5 km/h relative to the shore. A boat moves in the same direction as the current at 4 km/h relative to the river. We need to calculate the velocity of the boat relative to the shore.

As the two vectors are going in same direction. So, the velocity of the boat relative to the shore can be calculated by adding the river's velocity to the boat's velocity. So, the correct option is (c) "add the river’s velocity to the boat’s velocity".

the answer is d. 4
