The current in a river is 1.0 meters/second. britney swims 300 meters against the current. if she normally swims with a speed of 2.0 meters/second in still water, how long does it take her to complete the trip?

t = 300 seconds

Explanation:

It is given that,

Speed of the current in the river,

Distance covered by Britney, d = 300 m

Speed of Britney,

It is mentioned that Britney swims against the current. Her downstream speed is given by :

v = 1 m/s

Let t is the time taken by her to complete her trip. t is given by :

t = 300 seconds

So, the time taken by her the complete her trip is 300 seconds. Hence, this is the required solution.

the results is a decrease in air temperature with an increase of altitude.
