Speed of a boat in still water is 24 km/hr and the speed of stream is 13 km/hr. What is the upstream speed (in km/hr) and downstream speed (in km/hr) of the boat?
Show answer & explanation
Correct answer: A
Explanation
Given:
Speed in still water = 24 km/h
Speed of the stream = 13 km/h
According to the formula:
Upstream speed = Speed in still water − Speed of the stream
Downstream speed = Speed in still water + Speed of the stream
Upstream speed = 24 − 13 = 11 km/h
Downstream speed = 24 + 13 = 37 km/h
11 km/h, 37 km/h
