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
Answer and Feedback
Answer:A
Feedback:Let the actual distance travelled be x km
then,x/10 = x + 20/14
14x = 10x + 200
4x = 200
x = 50 km.
then,x/10 = x + 20/14
14x = 10x + 200
4x = 200
x = 50 km.
