Detailed Solution
Download Solution PDFGiven Data:
Distance downstream = 88 km
Time downstream = 11 hours
Distance upstream = 72 km
Time upstream = 12 hours
Concept:
Speed downstream = Distance downstream/Time downstream.
Speed upstream = Distance upstream/Time upstream.
Calculation:
Speed downstream = 88/11 = 8 km/hr
⇒ Speed upstream = 72/12 = 6 km/hr
⇒ Speed of the current = (8 - 6)/2 = 1 km/hr
Therefore, the speed of the current is 1 km/hr.
