Answer 2

Answer: Talia swims about 1.5 miles per hour faster than Alina.

Step-by-step explanation: There are 3600 seconds in an hour so

1.8 x 3600 =6480

6480 divide by 1609 = 4.02 miles / hr

4.02 - 2.5 = 1.5 (by substracting the speed). This arrives at the answer that Talia swims 1.5 miles faster.
