A body is travelling due east at a speed of 15km/h for one hour and then turns towards south at a speed of 10km/h for one hour. Find the average velocity of the body.

Explanation

To find the average velocity of the body, we will follow these steps:

### Step 1: Identify the Displacement in Each Direction
1. The body travels due east at a speed of 15 km/h for 1 hour.
- Displacement in the east direction (OA) = Speed × Time = 15 km/h × 1 h = 15 km.
2. The body then turns south and travels at a speed of 10 km/h for 1 hour.
- Displacement in the south direction (AB) = Speed × Time = 10 km/h × 1 h = 10 km.
