Download Solution PDFGiven:
Downstream = 24 km
Upstream = 8 km
Time taken = 4 hours
Formula used:
Speed of current = 1/2 × (Downstream - Upstream)
Calculation:
According to Question
Rate of downstream = 24/4 = 6 km/hr
Rate of Upstream = 8/4 = 2 km/hr
Speed of current = 1/2 × (Downstream - Upstream)
⇒ 1/2 × (6 - 2)
⇒ 1/2 × (4)
⇒ 2 km/h
∴ The speed of the current is 2 km/h.
