5h * 8 km/h = 40 km
Assuming the tug speed is relative to the river flow and is constant over each trip, and the river flows at the same constant rate during the trips, then: Let the flow rate down river be x mph Then the land speed when going upriver is 10 - x mph and the land speed when going down river is 12 + x mph This gives the total time for the journeys: time = distance/speed → 5½ hours = 24 miles/(10 - x)mph + 24 miles/(12 + x)mph → 11/2 = 24(12 + x + 10 - x)/(10 - x)(12 + x) → 11/2 = 24×22/(120 - 2x - x²) → 120 - 2x - x² = 24×22×2/11 → x² + 2x - 120 + 96 = 0 → x² + 2x - 24 = 0 → (x - 4)(x + 6) = 0 → x = 4 or -6 → The river is flowing at 4 mph down the river or 6 mph up the river. If the river is non-tidal, then the river is flowing at 4 mph down the river. (In river terms, up is towards the source of the river, down is towards the mouth of the river, and for a tidal river, eg the Thames between Richmond and its mouth, the current can be flowing up or down the river - the rate will not be constant, but for a period of time whilst the tide is flowing in one direction can be considered to be constant.)
mississippi river
The mouth part of a river is called a delta. It is the large silty area at the mouth of a river at which the river spills into different slow flowing channels.
Call the unknown speed of the current c and the speed of the boat in still water b. When travelling upstream, the net speed of the boat will be b - c and when travelling downstream the net speed of the boat will be b + c. Since b = 4c, the speed upstream will be 3c. The distance upstream is one-half the total travelling distance of 150 km or 75 kilometers. Distance travelled = speed X time at speed, so that upstream time = 75/3c, downstream time = 75/5c, and the sum of these is the total time stated to be 8 hours. Thus 75/3c + 75/5c = 8. Multiplying both sides by 15c yields 75(5 +3) = 120c, or c = (8 X 75)/120 = 5 kilometers per hour.
River Nile and the Jordan.
The river was called Ashvanadi, where Kunti floated her son born from Surya, named Karna.
it is the riga baby
Mississippi
he traveled from France to Mississippi River
BC's gold originally came from Quesnel river and floated downstream to caribou river.
No, the story of Jesus being floated down the river as a baby is not part of traditional Christian beliefs. In the Bible, Jesus was born in Bethlehem and later traveled to Egypt to escape King Herod's persecution.
it is precisley THE ORINCO RIVER
The wagons were made of wood and floated behind the horses if it was nessary.
The Mayflower..
The mother of Moses put him in a basket, and out him in the river Nile.
