ANS. => none of the above
999 I think... let me know if that is correct:)
Answer: Option 'D' is correct.
Step-by-step explanation:
Since we have given that
Rate at which Alina swim = 2.5 miles per hour
Rate at which Talia swim = 1.8 meters per second
First we need to change meters per second into miles per hour
As we have given that

and

So, to change into miles per hours, we'll apply this,

So,
Difference between their rates will be given by

Hence, Talia swims about 1.5 miles per hour faster than Alina.
So, Option 'D' is correct.
The point slope equation should be y+1=2(x-6)
