Detailed Solution
Download Solution PDFGiven
Speed of boat in still water = 30 km/h
Speed of current = 6 km/h
Formula used
Distance = Speed × Time
Upstream speed = Speed of boat - Speed of current
Calculation
Upstream speed = (30 - 6)km/h
⇒ 24 km/h
Distance covered in 1 hour (60 minutes) = 24 km
Distance covered in 1 minutes = (24/60) km
Distance covered in 5 minutes = (24/60) × 5 km
⇒2 km
∴ The distance (in km) travelled upstream in 5 minutes is 2 km.
