### Discussion :: Time and Distance

1. 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:

2. A.
 50 km
B.

56 km

C.

70 km

D.

80 km

Explanation :

Let the actual distance travelled be x km.

Then,$$\frac { X } { 10 }$$=$$\frac {X+20 } { 14 }$$

14x = 10x + 200

4x = 200

x = 50 km.
