Description for Correct answer.
A boat runs at 22 km. The speed will the boat run against a current of 8 kmhr in order to go a given distance most economically is 12 kph. Speed downstream Speed of Boat in still water Speed od the stream 134kmhr 17kmhr. 3 36u 12v 6.
Cox drives her speed boat 22 km at 45 kmhr. 2900 mi at 12 knots 22 kmh. Let the speed of the current be x kmhr.
Find the speed of the boat in still water. Calculating Boat Fuel Consumption. Speed of the stream 4 kmh.
The speed of a boat is 18 kmhr in upstream and the speed of the stream is 6 kmhr. Time taken to travel 68 km downstream S peedDistance. Your boats fuel consumption is not nearly as easy to figure out compared to your car or truck.
Or 12u 8v 3. Let speed of the boat in still water a and speed of the stream b Then a b 14 a - b 8 Adding these two equations we get 2a 22 a 11 ie speed of boat in still water 11 kmhr. Or 6u 2v 1.
Put in the above equation we get 24u 16v 6. Find out the speed of the boat. Downstream speed x y kmhr.
