How long will it take to canoe three miles?
Half an hour down stream one and a half hours upstream if the water is running at about 1 mile an hour.
If the current flows at 2 mph and it takes me 3 hrs. to row 9 miles upstream how long will it take for me to return?
To find how long it will take to return downstream, first determine the effective speed while rowing upstream. The current speed is 2 mph, so your effective speed upstream is your rowing speed minus the current. If it takes 3 hours to row 9 miles upstream, your rowing speed is 5 mph (since 9 miles / 3 hours = 3 mph, and 3 mph + 2 mph = 5 mph). While returning downstream, your effective speed will be 5 mph + 2 mph = 7 mph. Thus, it will take 9 miles / 7 mph = approximately 1.29 hours, or about 1 hour and 17 minutes, to return downstream.
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.
A motorboat takes 5 hours to travel 300 km going upstream The return trip takes 2 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Velocity = Distance ÷ Time.The speed upstream = 300 ÷ 5 = 60kph.The speed downstream = 300 ÷ 2 = 150 kph.The speed upstream equals boat velocity(Vb) minus current velocity(Vc).The speed downstream equals boat velocity (Vb) pluscurrent velocity (Vc).Vb - Vc = 60Vb + Vc = 150 : Adding the two equations together gives :-2Vb = 210 : Vb = 105, therefore Vc = 45The rate of the boat in still water is 105 kph. The rate of the current is 45 kph.
Heading north with the Gulf Stream a cruise ship traveled 300 miles in 15 hours against the current it took 30 hours to make the return trip what is the speed of the ship in still water?
15 miles
A person can row downstream 20km in 2 hours and upstream 4km in 2 hours. find the speed of the current?
To do this, you need to form equations using the information given. There are 2 variables here, the base speed of the rower with no current (x), and the speed of the current (y). Firstly, convert the distances and times given into average speeds. 20km/2 hours = 10km/h 4km/2 hours = 2km/h The actual speed = the base speed +- the current, depending on direction. So 10 = x + y 2 = x - y If we subtract these 2 equations to eliminate x, we get: 8 = 2y y = 4km/h
A sailor goes 8km downstream in 40 minutes and returns in 1 hours Determine the speed of the sailor in still water and speed of the current?
Let speed of stream = y kmph & speed of boat = x kmphspeed downstram((x + y)kmph) = 8 * 60 / 40 kmph= 12 kmphspeed upstream((x - y) kmph) = 8/1 kmph= 8 kmphx + y = 12x - y = 8--------------2x = 20,2y = 4x = 10,y = 2=>Speed of stream = 2 kmph, Speed of boat = 10 kmp
