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
