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

qwelly [4]

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

2x - 5 < 33 what are all the values to this inequality

Lynna [10]

Answer:

x < 19

Step-by-step explanation:

Given that,

An inequality 2x - 5 < 33.

LHS of the inequality is 2x - 5

RHS of the inequality is 33

LHS < RHS

i.e.

2x - 5 < 33

Add 5 to both sides of the inequality

2x - 5 +5 < 33+5

2x < 38

Divide both sides by 2.

x < 19

So, the value of x is less than 19.
