The speed of a boat in still water is 44 km/hr and the speed of a stream is 26 km/hr. Find the upstream speed of boat.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 18 km/hr.
Given:
Speed of boat = 44 km/h
Speed of stream = 26 km/h
Formula used:
Upstream speed = (x - y) km/h
Where x = speed of boat and y = speed of stream
Calculations:
According to the question;
⇒ Upstream speed = (44 - 26)
⇒ 18 km/h
