boat sails a distance of 44 km in 4 7 with the current it takes 4 hours 48 minutes to cover the same distance again second find the speed of the boat in still water and the speed of current
Answers
Let say Speed of Boat in Still water= B km/Hr
Let say speed of Current = C km/Hr
Speed with Current = B + C km/Hr
Distance = 44 km
Time taken = 4 Hrs
Speed = Distance / Time
=> B + C = 44/4
=> B + C = 11
Speed against Current = B - C km/Hr
Distance = 44 km
Time taken = 4 + 4 Hrs 48 minutes = 8 4/5 = 44/5 hrs
Speed = Distance / Time
=> B - C = 44/(44/5)
=> B - C = 5
Adding Both 2B = 16 => B = 8
8 + C = 11 => C = 3
Speed of Boat in still water = 8 km/Hr
Speed of current = 3 km/hr
Answer:
8 & 3 km/Hr
Step-by-step explanation:
Let say Speed of Boat in Still water= B km/Hr
Let say speed of Current = C km/Hr
Speed with Current = B + C km/Hr
Distance = 44 km
Time taken = 4 Hrs
Speed = Distance / Time
=> B + C = 44/4
=> B + C = 11
Speed against Current = B - C km/Hr
Distance = 44 km
Time taken = 4 + 4 Hrs 48 minutes = 8 4/5 = 44/5 hrs
Speed = Distance / Time
=> B - C = 44/(44/5)
=> B - C = 5
Adding Both 2B = 16 => B = 8
8 + C = 11 => C = 3
Speed of Boat in still water = 8 km/Hr
Speed of current = 3 km/hr
