Detailed Solution
Download Solution PDFGiven data:
Speed of boat in still water = 17 km/hr
Speed of stream = 11 km/hr
Concept: Upstream speed = Boat speed - Stream speed
Downstream speed = Boat speed + Stream speed
Solution:
⇒ Upstream speed = 17 - 11 = 6 km/hr
⇒ Downstream speed = 17 + 11 = 28 km/hr
⇒ Difference = Downstream speed - Upstream speed = 28 - 6 = 22 km/hr
∴ The difference between the upstream and downstream speed of the boat is 22 km/hr.
