Given : A boat in still water has a speed of 8.5 m/s. The boat is moving upstream in a river with flow speed of 5 m/s
To find : ground speed of boat.
Solution:
Boat speed in still water = 8.5 m/s
Flow Speed = 5 m/s
Boat speed upstream = Boat Speed in still water - Flow speed
=> Boat speed upstream = 8.5 - 5
=> Boat speed upstream = 3.5 m/s
Boat speed upstream is relative to ground
Hence ground speed of boat. = 3.5 m/s
