Distance = speed / time.
Then time = distace/ speed.
Speed = boat speed+stream speed.
Speed = 13+4=17 distance = 68.
D = 68/17 = 4hrs.
Then time = distace/ speed.
Speed = boat speed+stream speed.
Speed = 13+4=17 distance = 68.
D = 68/17 = 4hrs.

13+4 = 17km/hr,
For 1 hour he goes 17 km.
Then for 68 km he takes 4 hrs.
For 1 hour he goes 17 km.
Then for 68 km he takes 4 hrs.

13+4 = 17km/hr.
Now, 48/17 = 4hr.
Now, 48/17 = 4hr.
