x = 4.6
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:

The <u>correct answer</u> is:
Line L must be perpendicular to both line O and line P as well.
Explanation:
Since N, O and P are all parallel, any line that intersects N will intersect O and P at the same angle. Since L is perpendicular to N, intersecting at a right angle, this means it must be perpendicular to O and P also.
