Detailed Solution
Download Solution PDFGiven:
Speed against the current (Upstream speed) = 18 km/hr
Downstream speed = 50% more than upstream speed
Formula used:
Downstream speed = Upstream speed × 1.5
Speed of stream = (Downstream speed - Upstream speed) / 2
Calculation:
Downstream speed = 18 × 1.5
⇒ Downstream speed = 27 km/hr
Speed of stream = (27 - 18) / 2
⇒ Speed of stream = 9 / 2
⇒ Speed of stream = 4.5 km/hr
∴ The speed of the stream is 4.5 km/hr.
