Answer: Reagan

Explanation:

Answer 2

Answer:

Jesse swims the fastest with the rate of 5.5 ft in 1 second.

Step-by-step explanation:

The swimming rate of Elizabeth is:   50 feet in 10 seconds

So, the swimming rate per second is $\frac{50}{10} = 5 ft$

⇒Elizabeth swims 5 ft in 1 second.

Similarly,the swimming rate of Jesse is:   110 feet in 20 seconds

So, the swimming rate per second is $\frac{110}{20} = 5.5 ft$

⇒Jesse swims 5.5 ft in 1 second.

Also,the swimming rate of Reagan is:   160 feet in 30 seconds

So, the swimming rate per second is $\frac{160}{30} = 5.33 ft$

⇒Reagan swims 5.33 ft in 1 second.

By comparing the per second rate of swimming,

5.5 is the greatest of the all rates.

Hence, Jesse swims the fastest with the rate of 5.5 ft in 1 second.
