If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. The actual distance travelled by him is:
Answer: Option
Explanation:
Let the actual distance travelled be x km.
| Then, | x | = | x + 20 |
| 10 | 14 |
14x = 10x + 200
4x = 200
x = 50 km.

Hey, friends.
This is the easiest way of thinking.
Let the distance travelled by walking at the speed of 10km/h be x.
Then the distance travelled by walking at the speed of 14km/h will be x+20(according to the question).
so, 14=x+20,
10=x.
Cross multiply and find the value of x.

If 10kmph will cover x distance than 14 will cover it faster. But why here 20 km is added to 14kmph distance. How can it be possible?

14:10
7:5
2 difference = 20,
So 20/2 = 10.
5*10 = 50 ans.

14-10 = 4km,
10*20 = 200,
200%4 = 50.
10*20 = 200,
200%4 = 50.

Your explanation is very clear. Thank you so much @Ilesh.

But it can be 70 also as it is said actual distance traveled by him x+20 where x is 50+20=70.

I agree @Ilesh.

Hello friends.
The person walks 14kmph instead of 10 km that means his original speed is 10kmph.
By walking 4kmph extra speed he covers 20 km.
That means for 1kmph he will cover 5 km.
Then for 10kmph, he will go 50 km. It's so simple.

Given data both are speed rate 1h. First take 1h =x/10, and second take 1h=x+20/14. Both are take time 1hour.
