When two velocities are in the same direction, you simply add them to find the resultant velocity. Here's how:

1. Understand the Concept:

* Velocity is a vector quantity, meaning it has both magnitude (speed) and direction.

* When velocities are in the same direction, they reinforce each other.

2. The Formula:

Resultant Velocity (V_r) = Velocity 1 (V₁) + Velocity 2 (V₂)

Example:

Imagine a boat traveling at 10 km/h eastward in a river that flows eastward at 5 km/h.

* V₁ = 10 km/h (boat's velocity)

* V₂ = 5 km/h (river's velocity)

Resultant Velocity (V_r) = 10 km/h + 5 km/h = 15 km/h eastward

Key Point:

The resultant velocity will have the same direction as the individual velocities. In this case, it's eastward.
