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.

I think the answer should be 70. Because the actual distance travld is 50+20=7.
Am I right?

14km/hr - 10 km/hr = 4 km/hr(difference)
4km/hr - 20km,
10km/hr (?),
= 10*20/4.
= 50km.
4km/hr - 20km,
10km/hr (?),
= 10*20/4.
= 50km.

14-10 = 4km/hr more at 14, 20km/hr extra distance.
20/4 = 5hrs.
5*14 = 70 is the answer.
20/4 = 5hrs.
5*14 = 70 is the answer.

@All.
14-10 = 4km/hr.
4km/hr = 20km travelled.
so 1hr = 5km,
then 10km/hr = 10 * 5 = 50.
14-10 = 4km/hr.
4km/hr = 20km travelled.
so 1hr = 5km,
then 10km/hr = 10 * 5 = 50.

Difference of speed 14-10 = 4.
Therefore 4 km ----> 20.
So 10 km to travels 50 km.
Therefore 4 km ----> 20.
So 10 km to travels 50 km.

I am not clear with the explanation and I didn't understand this step x/10=x+20/14.

Hi, friends.
Here both times are equal for traveling x, and x+20 so x/10 =x+20/14.

Extra 4kmhr------20km more.
So 1kmhr------ ?
20*1/4 so = 5.
so 10km*5 = 50.
So 1kmhr------ ?
20*1/4 so = 5.
so 10km*5 = 50.

I'm not clear with the answer. Why did you take the time same in both the cases?
