Answer:

The Jesse swim fastest

Step-by-step explanation:

Given as :

The distance cover by Elizabeth while swimming = 50 feet

The time taken by Elizabeth = 10 sec

So, Speed of Elizabeth = \frac{Distance}{Time}

∴    Speed of Elizabeth = \frac{50}{10} = 5 feet per sec

Again ,

The distance cover by Jesse while swimming = 110 feet

The time taken by Jesse = 20 sec

So, Speed of Jesse = \frac{Distance}{Time}

∴    Speed of Jesse = \frac{110}{20} = 5.5 feet per sec

Again ,

The distance cover by Reagan while swimming = 160 feet

The time taken by Reagan = 30 sec

So, Speed of Reagan = \frac{Distance}{Time}

∴    Speed of Reagan = \frac{160}{30} = 5.3 feet per sec

So, Speed of Elizabeth< Speed of Reagan < Speed of Jesse

Hence The Jesse swim fastest   Answer
