Answer:
104km.
Step-by-step explanation:
Boat travels 18 km more in downstream in 3hrs.
Boat travels 18/3km more in downstream in 1 hr.
Speed of boat in still water=20 km/hr.
Therefore speed of boat in downstream=(20+6) =26km/hr.
Therefore distance traveled by boat in downstream in 4hr=(26×4) =104km
