Veckat went to his collage from his house on his car with a unifrom speed of 60 km` h^(-1)` and returns to his house with a different speed. If the average speed of the car, for whole journey is `50 km^(h-1)` , then find the speed of his car when it travelled from college to house.

Explanation

To find the speed of Veckat's car when he returned from college to his house, we can follow these steps:

### Step 1: Define the Variables
Let the distance from Veckat's house to college be \( d \) kilometers. The speed from house to college is given as \( 60 \, \text{km/h} \), and we will denote the speed from college to house as \( x \, \text{km/h} \).

### Step 2: Calculate Time for Each Journey
- The time taken to go from house to college:
\[
