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:

50 km
56 km
70 km
80 km

Correct Answer: 50 km

Explanation:

Let the actual distance travelled be x km.

Then,	x	=	x + 20
	10		14

⟹ 14x = 10x + 200

⟹ 4x = 200

⟹ x = 50 km.
