Question

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 statement comparing the two swimmers is accurate?

Answer 1

Answer:

Talia swims about 1.52 miles per hour faster than Alina.

Step-by-step explanation:

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.

First we will change meters per second into miles per hour.

1 mile= 1609.34 meters

1 hour = 3600 seconds

So, 1.8 meters per second will be = $\frac{1.8*3600}{1609.34}$

= 4.02 miles per hour.

Now, the difference between their rates is = $4.02-2.5=1.52$ miles per hour.

Therefore, Talia swims about 1.52 miles per hour faster than Alina.

Answer 2

Talia swims about 1.5 mph faster than Alina
