Question
Find the total distance covered by boat in still water
in 8 hours if the speed of boat in upstream and in downstream is 10 km/h and 15 km/h respectively?Solution
Speed of boat in upstream = 10 km/hr Speed in downstream = 15 km/hr Speed of boat in still water = 12.5 km/hr Required total distance= 12.5 × 8 = 100 km
