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? 1 mile approximately equal to 1,609 meters

Convert Talia’s speed to miles per hour: 1.8 meters per second × 3,600 seconds per hour ÷ 1,609 meters per mile ≈ 4.0 miles per hour. Compared with Alina’s 2.5 miles per hour, Talia is about 4.0 − 2.5 = 1.5 miles per hour faster. So the accurate statement is that Talia swims about 1.5 miles per hour faster than Alina.
