Alina is able to swim at a rate of about 2.5 miles per hour. Talia is able to swim at a rate of 1.8 meters per second. Which sta
Masja [62]

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

1\text{ miles}=1609\text{ meters}

and

1\text{ hour}=3600\text{ seconds}

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

\frac{1.8\times 3600}{1609}\\\\=4.02\text{ miles per hour}

So,

Difference between their rates will be given by

4.02-2.5=1.52\text{ miles per hour}

Hence, Talia swims about 1.5 miles per hour faster than Alina.

So, Option 'D' is correct.
