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:

Options:
A .  50 km
B .  56 km
C .  70 km
D .  80 km
Answer: Option A

Let the actual distance travelled be x km.


Then,\(\frac{x}{10} = \frac{x+20}{14}\)


14x = 10x + 200


4x = 200


 x = 50 km.
