What is the correct answer?

4

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:

A. 50 km

B. 56 km

C. 70 km

D. 80 km

Correct Answer :

A. 50 km


Let the actual distance travelled be x km.
Then, x10 = x + 2014
14x = 10x + 200
4x = 200
x = 50 km.
