If a person walks at 14 km/hr instead of 10 km/hr, he would have walked 20 km more. What is the actual distance travelled by him?	Choose the correct choice from the following options:
A) 33
B) 11
C) 38
D) 50
E) 12
Assume that the person would have covered x km if travelled at 10 km/hr   ⇒Speed = 50istanceTime=x10.....(Equation1)   Give that the person would have covered (x + 20) km if travelled at 14 km/hr   ⇒Speed = 50istanceTime=(x+20)14.....(Equation2)   From Equations 1 and 2,   x10=(x+20)1414x=10x+2004x=200x=2004=50   Answer : 50
