A boat can travel with a speed of 22 km/hr in still water.
A boat can travel with a speed of 22 km/hr in still water. If the speed of the stream is 5 km/hr, find the time taken by the boat to go 189 km downstream
Answer/Solution
7 hours
Steps/Work
Explanation :
Speed of the boat in still water = 22 km/hr
speed of the stream = 5 km/hr
Speed downstream = (22+5) = 27 km/hr
Distance travelled downstream = 189 km
Time taken = distance/speed = 189/27 = 7 hours. Answer : Option E
Speed of the boat in still water = 22 km/hr
speed of the stream = 5 km/hr
Speed downstream = (22+5) = 27 km/hr
Distance travelled downstream = 189 km
Time taken = distance/speed = 189/27 = 7 hours. Answer : Option E
