speed of boat in still water=11 km/hr
distance=12 km
total time= 2 hrs 45 mins = 11/4
let the speed of stream be x and
the time taken by boat in still water be y 12/11=y 12/(11+x) + 12/(11-x)=11/4 (132-12x+12x+132)/121-x2 =11/4 264=1331-11x2/4 1056=1331-11x2 1331-1056=11x2 275=11x2 25=x2 5=x therefore, the speed of the stream is 5 km/hr!
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.
it is ternary form
Whilst travelling downstream the boat travels at V + C mph where V is the speed of the boat in still water and C is the speed of the current. Whilst travelling upstream the speed is V - C mph. The downstream velocity = 24/2 = 12mph = V + C therefore C = 12 - V Velocity (speed) = Distance ÷ Time : therefore Distance = Velocity x Time. As the distance in either direction is the same then, 2(V+C) = 3(V-C) 2V + 2C = 3V - 3C V = 5C : substituting for C as C = 12-V V = 5(12 - V) = 60 - 5V 6V = 60 : V = 10 mph. Therefore, C = 12 - 10 = 2 mph The speed of the boat in still water is 10 mph and the speed of the current is 2 mph.
A current yield is a bond's annual return based on its current price. This is different from its original price and face value.
Method 1: Sort the array in descending order, compare 1st and 2nd if not same , return 2nd if same return -1 Method 2: Find the largest number in the array, initialize another array with dimension 1 less than of original. Copy the array elements from the original array minus the largest element. not select largest from the second array and compare with the previous one if not same return the second largest if same return -1
The current is approximately 4 mph.
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.
The people downstream.
Boats speed = 24 miles per hour.Current speed = 4 miles per hour.
both but read the original first then the return cause the original leads up to the return series
Fish swim upstream by powerfully thrusting their tails to counteract the current. They are then able to slowly but surely travel upstream.
This is a channel marker, placed on the edge of a channel. Green markers will always have an odd number on them. If you are heading upstream it should be to your left. If you are heading downstream it should be to your right. It will be opposite a red marker or bouy with an even number on it. To aid in navigating, the term "red, right, returning" is used meaning as you return from open waters (head upstream), the red marker, bouy, sign etc, should be to your right. That means the green one, in your example with a 3 on it, should be to your left. If its on your right side, you are outside the cleared channel area.

Salmon swim upstream to live out their adult lives. The thing that helps them to swim upstream is purely will power and instinct. They are taught all of their lives to swim to the ocean when they are adults and return to the river where they were born to give birth and die.
They go on it because it is the fate of their life. They are born to travel to the ocean and then come back lay their eggs and die. Them dieing supports many species and the forest its self. It is a very interesting story. Check this page out http://www.squidoo.com/TheSalmonRun
