If a person walks at 14km/hr instead of 10km/hr, he would have walked 20km more.the actual distance travelled by him is

Let's denote the actual distance travelled by the person as \( d \) kilometers and the time taken to travel this distance as \( t \) hours.

Given:
- Walking speed at first is \( 10 \) km/hr.
- Walking speed at second is \( 14 \) km/hr.
- If walking at 14 km/hr, the person would have walked 20 km more.

We set up the following relationships:

1. Distance \( d \) travelled at 10 km/hr:
\[ d = 10t \]

2. Distance \( d + 20 \) travelled at 14 km/hr:
\[ d + 20 = 14t \]

We now have two equations:
\[ d =
