Answer:
t = 300 seconds
Explanation:
It is given that,
Speed of the current in the river, \(v_1=1\ m/s\)
Distance covered by Britney, d = 300 m
Speed of Britney, \(v_2=2\ m/s\)
It is mentioned that Britney swims against the current. Her downstream speed is given by :
\(v=v_2-v_1\)
\(v=2-1\)
v = 1 m/s
Let t is the time taken by her to complete her trip. t is given by :
\(t=\dfrac{d}{v}\)
\(t=\dfrac{300\ m}{1\ m/s}\)
t = 300 seconds
So, the time taken by her the complete her trip is 300 seconds. Hence, this is the required solution.
