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 Options
A) 48 km	B) 50 km	C) 40 km	D) 22 km	E) 70 km
B   50 km.   Let the actual distance travelled be x km.   Then x/10=(x+20)/14   --&gt; 14x = 10x + 200   --&gt; 4x = 200   --&gt; x = 50 km.
