Answer:
5 km/h
Step-by-step explanation:
In this problem, Lashonda swam 4 km against the current. So the distance covered in this case is
Calling the velocity of Lahonda without the current, and
the velocity of the current, in this situation Lahonda's velocity is
So we can write:
where is the time taken to cover the distance.
When Lashonda swims with the current, her velocity is
So we can write
where
is the distance covered in this case, and
the time taken.
The velocity of the current is
Since Lashonad takes the same time to cover the two distances,
So we can write
And solving for v, we find Lashonda's velocity without the current:
