A car travels first half distance between two places with a speed of 40 km/h and the rest half distance with a speed of 60 km/h. The average speed of the car will be-

Options

A. 100 km/hr
B. 50 km/hr
C. 49 km/hr
D. 200 km/hr

Explanation

To find the average speed of the car that travels half the distance at 40 km/h and the other half at 60 km/h, we can follow these steps:

### Step 1: Define the total distance
Let the total distance between the two places be \( D \). Therefore, the first half distance is \( \frac{D}{2} \) and the second half distance is also \( \frac{D}{2} \).

### Step 2: Calculate time taken for each half
- **Time for the first half**:
\[
