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

What are the dimensions of a rectangle with an area of 45 square inches and a perimeter of 28 inches? A) 8 in. x 6 in.B) 9 in. x

grigory [225]

Length be x
Breadth be y

$\\ \rm\Rrightarrow 2x+2y=28$

$\\ \rm\Rrightarrow x+y=14$ --(1)

And

xy=45

$\\ \rm\Rrightarrow (x-y)^2=(x+y)^2-4xy$

$\\ \rm\Rrightarrow (x-y)^2=14^2-4(45)=196-180$

$\\ \rm\Rrightarrow (x-y)^2=16$

$\\ \rm\Rrightarrow x-y=4$ --(2)

Adding (1) and (2)

2x=18
x=9

And

9+y=14=>y=5
