Keep it on your starboard side.
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?
keep the buoy on the starboard side
2 miles per second upstream relative to the river bank.Note: This is quite a scenario, even for experienced rapids-shooters.That river is flowing at 28,800 miles per hour, and the guy is paddlinghis kayak through the water at 36,000 miles per hour. The whole sceneis definitely poised to launch itself into solar orbit.
I am not sure of the answer but it is not a delta since a delta need not be marshy and the question asks about marshy land.
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
If you are traveling upstream on a river and see a red triangular daymark, you should pass this marker on the left side.
When traveling upstream on a river you see a red triangular daymark, so you should pass on the left side.
Leave that mark to starboard.
::Keep the marker on your starboard (right) side
You are boating near shore at twilight. You see a square-shaped daymark. You cannot make out the marker's color. What color is it?

ans is = 10 - 8 = 2 m/s (upstream)
Downstream. The source of a river is always upstream.
