A is faster than B. A and B each walk 24 km. The sum of their speeds is 7 kmph and the sum of times taken by them is 14 hours. Then, A's speed is equal to:

Answer»

3 kmph



Let A's SPEED = X kmph , Then B's speed = (7 - X) kmph
So, 24/X + 24/(7 - X) = 14
After solving the equation , we GET X = 3 , 4
Since, A is faster than B, So A's speed = 4 kmph and B's speed = 3 kmph.
