Q:

A man walks at a speed of 3 kmph. He doubles his speed after reaching exactly half way. He walks for 5 hours in all. What is the total distance travelled by him?

A) 19 km	B) 15 km
C) 12 km	D) 20 km

Let total distance be 2D.

He walks half distance i.e, (2D/2) = 'D' distance with 3 kmph and

The next 'D' with 6 kmph.

Using formula,

(D/3) + (D/6) = 5

D =10 ,

Hence, Total distance 2D = 20 kms.
