Answer:

example

Step-by-step explanation:

speed of the boat=8 km/hr

speed of the stream=3 km/hr

If the speed of the boat in still water is x km/hr and speed of the stream is y km/hr then speed upstream=(x−y) km/hr

Therefore speed upstream=8−3=5 km/hr

distance=30 km

time=

speed

distance

⇒time=

5

30

⇒time=6 hrs
