On a canoe trip, Rita paddled upstream (against the current) at an average speed of 2mi/h relative to the riverbank. On the return trip downstream (with the current), her average speed was 3 mi/h. Find Rita's paddling sp eed in still water and the speed of the river's current.

Paddling speed = 2.5mi/h

speed of current = 0.5mi/h

Step-by-step explanation:

Given that :

Paddling upstream against current (paddling speed - speed of current)

Let paddling speed be, x ; current speed = c

x - c = 2mi/h - - - (1)

Return downstream (paddling speed + speed of current)

x + c = 3mi/h - - - - (2)

Add (1) and (2)

2x = 5

x = 5/2 = 2.5

Paddling speed = x = 2.5mi/h

Speed of current :

From;

x + c = 3

2.5 + c = 3

c = 3 - 2.5

c = 0.5

c = speed of current = 0.5mi/h

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

describing distributions is one of the key skills you’ll need to earn a high score on the ap statistics exam. if you need proof of this, just flip through some past exam questions, which can be found at the collegeboard website. you’ll notice that the first free response question is almost always a question requiring you to look at a graph and describe it.
