Anand can row a boat in still water at a speed of 5 km/hr. The speed of the stream is 3 km/hr. How much time (in hours) will he take to row 40 km downstream?
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → 5
Going downstream, the stream speed is added to the speed of the boat in still water.
Downstream speed \(=5+3=8\) km/hr
Time for 40 km \(\displaystyle =\frac{40}{8}=5\) hr
