### Discussion :: Boats and Streams

1.  A boat can travel with a speed of 13 km/hr in still water. If the speed of the stream is 4 km/hr, find the time taken by the boat to go 68 km downstream.
2.  A. 2 hours B. 3 hours C. 4 hours D. 5 hours

Answer : Option C

Explanation :

Speed downstream = (13 + 4) km/hr = 17 km/hr.

 Time taken to travel 68 km downstream =$$[\frac { 68 } {17 }]$$hrs = 4 hrs.
