my kickstand on my bike broke so i used a tire patch kit to fix it last time
^hate pricks like him/her this is the correct answer: ADSL
2 Miles An Hour.
The current flows at 4 kph.The boat motors at 11 kph.
The speed upstream is B - C where B is the speed of the badge in still water and C is speed of the current The speed downstream is B + C. Velocity = Distance/Time : therefore Time = Distance/Velocity. Time for upstream journey = 6/(B - C) Time for downstream journey = 6/(B + C) BUT Total time for journey = 2 = 6/(B - C) + 6/(B + C) = 12B/(B2 - C2) Therefore 2B2 - 2C2 = 12B : However, B = 8kph so substituting gives, 128 - 2C2 = 96 : 2C2 = 32 : C2 = 16 : C = 4 The speed of the current is 4kph.
Call the unknown speed of the current c and the speed of the boat in still water b. When travelling upstream, the net speed of the boat will be b - c and when travelling downstream the net speed of the boat will be b + c. Since b = 4c, the speed upstream will be 3c. The distance upstream is one-half the total travelling distance of 150 km or 75 kilometers. Distance travelled = speed X time at speed, so that upstream time = 75/3c, downstream time = 75/5c, and the sum of these is the total time stated to be 8 hours. Thus 75/3c + 75/5c = 8. Multiplying both sides by 15c yields 75(5 +3) = 120c, or c = (8 X 75)/120 = 5 kilometers per hour.
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

downstream and upstream
assembly upstream and downstream in ammetres
Upstream is where the flow is coming FROM . -Downstream is the direction it is going to.
Downstream
Downstream. The source of a river is always upstream.
upstream
The closer to th engine is upstream and the farther is downstream Before the cat upstream After the cat downstream.
Upstream and downstream systems are business terms that apply to the production process. The search for and extraction of raw materials refers to upstream. When these materials are processed refers to the downstream.
Upstream and downstream refers to the supply chain of an industry. For example, if you're looking at a distribution plant then the manufacture would be downstream and the retailer would be upstream. Events or processes that happen before whatever is being looked at is downstream and whatever happens after is upstream.
