speed of boat in still water = 13km/h
speed of boat in downstream = 13 +4 = 17km/h
now,
time taken by boat to travel 68 km
= distance / speed
= 68/ 17
= 4 hours. :)
speed of boat in downstream = 13 +4 = 17km/h

time taken by boat to travel 68 km
= distance / speed
= 68/ 17

Speed of boat in still water = 13 km /hr
Speed of the stream = 4 km/hr
Total speed = 13 + 4 = 17 km/hr
Time = distance / speed
distance = 68 km
time = 68 / 17
= 4 hours
Speed of the stream = 4 km/hr
Total speed = 13 + 4 = 17 km/hr
Time = distance / speed
distance = 68 km
time = 68 / 17
= 4 hours
