29 km per hour.
The time it takes to travel 2,500 kilometers by boat depends on the boat's speed. For example, if the boat travels at an average speed of 10 knots (about 18.5 km/h), it would take approximately 135 hours or about 5.6 days. At a faster speed of 20 knots (around 37 km/h), the journey would take about 67 hours or around 2.8 days. Therefore, the duration can vary significantly based on the vessel's speed and conditions.
Suppose the speed of the boat is x mph. Then upstream, it travels 5 hours at x-3 mph and so covers 5x - 15 miles. When going downstream the boat covers the same distance, at x+3 mph, in 2.5 hours so (5x-15)/(x+3) = 2.5 Multiply through by 2*(x+3): 2*(5x-15) = 5*(x+3) 10x - 30 = 5x + 15 or 5x = 45 giving x = 9 mph.
The average speed of boat in kilometers is per hour is 20 km /hr.
A fisherman travels downstream at full speed to his favorite fishing spot. The stream is running at a rate of 5 miles per hour, and the trip takes 2 hours to get to the fishing hole. He is surprised, however, to find that the trip takes 6 hours at full speed to get back to the dock when he is finished. How fast will his fishing boat go? the boat is going 30 mph.
10 miles per hour speed is not a vector quantity, therefore direction does not matter. 16 miles/ 2 hours=8 mph 24 miles/ 2 hours=12 mph (8+12)/2=10 mph average
5hours
To find the average speed of the boat traveling downstream, you can use the formula: speed = distance/time. The boat traveled 12 kilometers in 6 hours, so the average speed is 12 km ÷ 6 hours = 2 km/h. Therefore, the boat's average speed is 2 kilometers per hour.
The time it takes to travel 2,500 kilometers by boat depends on the boat's speed. For example, if the boat travels at an average speed of 10 knots (about 18.5 km/h), it would take approximately 135 hours or about 5.6 days. At a faster speed of 20 knots (around 37 km/h), the journey would take about 67 hours or around 2.8 days. Therefore, the duration can vary significantly based on the vessel's speed and conditions.
The speed of the boat is 26.67 miles per hour. This is calculated by dividing the distance traveled (20 miles) by the time taken (45 minutes converted to hours, which is 0.75 hours).
15 MPH. On the way up the river subtracts from the speed of the boat so the time is 40/10 or 4 hours. On the way back the river adds to the speed of the boat so the time is 40/20 or 2 hours. The total time is 6 hours.
Suppose the speed of the boat is x mph. Then upstream, it travels 5 hours at x-3 mph and so covers 5x - 15 miles. When going downstream the boat covers the same distance, at x+3 mph, in 2.5 hours so (5x-15)/(x+3) = 2.5 Multiply through by 2*(x+3): 2*(5x-15) = 5*(x+3) 10x - 30 = 5x + 15 or 5x = 45 giving x = 9 mph.
Information about the speed of the car provides no information whatsoever about the speed of a boat!
45 minutes in ¾ of an hour, so just divide 15 kilometers by ¾ hours and get 20 kilometers per hour.
Well, isn't that just a happy little question! If a boat travels 10 miles in 30 minutes, we can find its speed by dividing the distance by the time. So, the boat is traveling at a speed of 20 miles per hour. Just imagine all the lovely scenery the boat must be passing by at that gentle pace!
The average speed of boat in kilometers is per hour is 20 km /hr.
The time it takes to boat 100 miles depends on the speed of the boat. For example, if a boat travels at an average speed of 20 miles per hour, it would take about 5 hours to cover that distance. Conversely, if the boat moves at 10 miles per hour, it would take 10 hours. Factors like weather conditions and water currents can also influence travel time.
The average speed is(4 x the number of nautical miles the boat traveled in that time) knots.
