A man goes upstream for a distance of 10 kms in 5 hours. Another man goes downstream for the same distance of 10kms in 3 hours. What is the difference of the speeds of the two men if the river speed is 0.5 Kms. (Round the answer to two decimals)

The man going upstream speed :
Speed = Distance /time
10/5 = 2km/h
Since the velocity of the river is 0.5 and the person is moving in the opposite direction, the speed equals to the difference of the two speeds :
Speed of the man will be : 2 + 0.5 = 2.5 km/h
The speed of the man going downstream :
10/3 = 3.333
Speed of this man is :
3.333 - 0.5 = 2.83km/h
The difference between the two speeds is :
2.83 - 2.5 = 0.33 km/h
