Question

Elizabeth swims 50 feet in ten seconds. Jesse swims 110 feet in 20 seconds. Reagan swims 160 feet in half a minute. Who swims fastest?

Answer 1

jesse

Explanation:

Answer 2

The Jesse swim fastest

Explanation:

Given as :

The distance cover by Elizabeth while swimming = 50 feet

The time taken by Elizabeth = 10 sec

So, Speed of Elizabeth =
`(Distance)/(Time)`

∴ Speed of Elizabeth =
`(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 =
`(Distance)/(Time)`

∴ Speed of Jesse =
`(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 =
`(Distance)/(Time)`

∴ Speed of Reagan =
`(160)/(30)` = 5.3 feet per sec

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

Hence The Jesse swim fastest Answer
