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

Talia swims about 1.5 miles per hour faster than Alina.

Step-by-step explanation:

Since, 1 miles = 1609 meter and 1 hour = 60 seconds,

⇒

⇒

Here, The speed of Alina = 2.5 miles per hour = 2.5 × 1609/3600

And, the speed of Talia = 1.8 meter per second,

Since 1.8 > 1.11736111

⇒ Talia swims faster than Alina.

And, the difference between their speeds = 1.8 - 1.11736111 = 0.68263889 meter per seconds

= 0.68263889× 3600/1609 miles per hour

= 1.52734618 miles per hour ≈ 1.5 miles per hour ,

⇒ Fourth option is correct.

Answer 2

Talia is faster as she can swim 6480 meters per hour which equals 4.02... miles so Talia can out pace the 2.5 mile per hour Alina
