X takes 3 hours more than Y to walk a distance of 30 km, but if X doubles his race, he is able to be ahead of Y by 1(1/2) hours, then the speed of their walking will be : 1. X's speed =10/3 km/hr, Y's speed = 5 km/hr 2. X's speed =5 km/hr, Y's speed = 10/3 km/hr 3. X's speed =10 km/hr, Y's speed = 5/3 km/hr 4. X's speed =5/3 km/hr, Y's speed = 10 km/hr
