- A boat can travel with a speed of 16 km/hr in still water.
Question 1:
A boat can travel with a speed of 16 km/hr in still water. If the rate of stream is 5 km/hr, then find the time taken by the boat to cover distance of 84 km downstream. A. 4 hours
Feedback it is very important to check, if the boat speed given is in still water or with water or against water.
Speed downstream = (16 + 5) = 21 kmph
Time = distance/speed = 84/21 = 4 hours
Speed downstream = (16 + 5) = 21 kmph
Time = distance/speed = 84/21 = 4 hours
B. 5 hours
C. 6 hours
D. 7 hours
