A boat can travel with a speed of 16 km/hr. in water. If the stream has a speed of 8 km/hr., then find the time taken by the boat to go 336 km downstream.
1). 14 hrs.
2). 12 hrs.
3). 18 hrs.
4). 10 hrs.
⇒ Speed of still water = 16 km/hr
⇒ Speed of stream = 8 km/hr
⇒ Speed of downstream = Speed of still water + speed of stream = 16 + 8 = 24 km/hr
⇒ time taken by boat to travel 336 km downstream = Distance/time = 336/24 = 14 hrs
∴ Time taken by boat to travel is 14 hours
