What is the greatest velocity that a boat on a river can attain if the boat's motor moves at 10 km per hr and the river's current is 8 km per hr?
Boat WRT land, downstream 10 + 8 = 18 KMH Boat WRT land, upstream 10 - 8 = 2 KMH Boat WRT water 10 KMH
What is the biggest obstacle to traveling by boat on the Congo River?
Shallow areas due to drought are the biggest obstacle to traveling by boat on the Congo River.

What are the velocity direction and magnitude of a boat traveling 3 miles per hour in a river flowing south at 4 miles per hour?
South, 1mph
If a boat can travel 3 miles per hour in still water it is in a river that flows south 4 miles if the boat heads eastward directly across the river what are the velocity directionand magnitude of the?
The magnitude of the velocity is sqrt(32 + 42) = sqrt(9 + 16) = sqrt(25) = 5 mph. The heading of the boat is 143.1301 degrees ie 53.1301 degrees South of East. NB: 53.1301 = arctan(4/3)
If a boat can go 20 miles per hours in still water and can go six miles downstream and 3 miles up stream in the same time how fast is the river?
assume river velocity = X mph boat velocity = 20 mph time to go 6 miles downstream = T1 time to go 3 miles upstream = T2 distance = time * velocity downstream: 6 mi = T1 * (boat velocity + river velocity) upstream: 3 mi = T2 * (boat velocity - river velocity) 6 = T1 * ( 20 + X ) 3 = T2 * ( 20 - X ) T1 * ( 20 + X ) = 2 * ( T2 * ( 20 - X ) ) since T1 = T2 then 20 + X = 40 - 2X 3X = 20 X = 6.67 thus, river velocity is 6.67mph
What do you do when traveling up a river on a boat and see a red triangular daymark?
Leave that mark to starboard.
A boat whose velocity through the water is 14 kmh is moving in a river whose current is 6 kmin relative to the riverbed The velocity of the boat relative to the riverbed must be between?
13.9 km hr
What is the resultant velocity of a boat if it travels south across a river at 14 km per hr. It encounters a current flowing from east to west at 9 km per hour?
The resultant velocity of a boat is 17 km/hr and the direction of the boat is SW.
8.0 m per s and a boat is traveling 10.0 m per s upstream what is the boats speed relative to the riverbank?
f a river current is 8.0 m/s, and a boat is traveling 10.0 m/s upstream, what is the boat's speed relative to the riverbank?
The boat is on the river the boat is in the river which one is correct?
The boat is on the river is correct
How do you get to the source of the nile river?
It would take you 33 hours and a half to complete the Nile River. (in a 20kph boat) The source of the river is the "White Nile" which connects to the "Blue Nile" and flows into the Delta as one.
