If a motorboat can go 8 miles downstream on a river in 20 mins if the return 8 miles upstream takes 30 minutes what is the speed of the current?
The current is approximately 4 mph.
Why does the Nile flows upstream?
It does not. Actually it does. I'm in 6th grade and learning about that.The Nile flows upstream because of gravity. The majority of the Nile runs south to north because of gravity. However, there are also parts of the river that run north to south, ex. about 200 miles in Sudan. At no point, however, can the river run upstream. Upstream by definition is opposite the flow of the river (Merriam-Webster).
A boat on the Missouri river took 2 hours to go 48 miles downstream. The boat took 3 hours to return the same distance upstream. Find the rate of the boat in still water and the rate of the current.?
Boats speed = 24 miles per hour.Current speed = 4 miles per hour.
A motorboat maintained a constant speed of 24 miles per hour relative to the water going 35 miles upstream and then returning the total time for the trip was 3.0 hours What is the speed of current?
The current speed is about 4 miles per hour.

If a river current is 8.0 miles per second and a boat is traveling 10.0 miles per second upstream what is the boat's speed relative to the riverbank?
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.
A motor boat can go 2 miles downstream on a river in 3 minutes it takes 15 minutes for the boat to go upstream the same 2 miles find the speed of the current?
Let boat speed = X and current speed = Y Downstream speed = boat speed plus current speed = X + Y Upstream speed = boat speed minus current speed = X -Y Downstream speed = 2 miles divided by 3 minutes = 2/3 miles per minute Upstream speed = 2 miles divided by 15 minutes = 2/15 miles per minute X + Y = 2/3 X - Y = 2/15 add equations 2X = 2/3 + 2/15 = 10/15 + 2/15 = 12/15 = 4/5 divide by 2 X = 4/10 = 2/5 use second equation and find Y as X -Y = 2/15 2/5 - Y = 2/15 6/15 - Y = 2/15 Y = 4/15 = current speed = 0.266 miles per minute
