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.

He travels 4 km/hr extra in the other case.
So if he traveled 20 km more in that case then it means the time he took would be time= distance/speed = 20/4= 5 hours. So now that we know the time he took, we can find the actual distance he traveled.
Distance= speed* time= 10*5= 50 km.
So if he traveled 20 km more in that case then it means the time he took would be time= distance/speed = 20/4= 5 hours. So now that we know the time he took, we can find the actual distance he traveled.
Distance= speed* time= 10*5= 50 km.

He travel 14kmph instead of 10kmph,
So,
14 - 10=4.
Walked 20km more(distance÷speed)=time.
20÷4=5.
Actual distance is 10 * 5=50km. (Distance=time*speed).
So,
14 - 10=4.
Walked 20km more(distance÷speed)=time.
20÷4=5.
Actual distance is 10 * 5=50km. (Distance=time*speed).

S=14km/hr d=20km
T=d/s, So, 14/20= 5hrs,
Now we have T=5hrs and s=10km/hr is the actual speed he needs to go.
S=10 T=5
Now, d= S x T.
=10*-5.
= 50 km.
That's all.
T=d/s, So, 14/20= 5hrs,
Now we have T=5hrs and s=10km/hr is the actual speed he needs to go.
S=10 T=5
Now, d= S x T.
=10*-5.
= 50 km.
That's all.
