If the boat upstream travels 30 m per our but the current is 10 against we do have 30-10=20 speed
So the time is 40/20=2 hours
Downstream we do have 30+10=40
The time is 40/40=1 hour
3 hours in total
So the time is 40/20=2 hours
Downstream we do have 30+10=40
The time is 40/40=1 hour
3 hours in total
