Answer:

5 1/12

Step-by-step explanation:

Your calculator will give you the repeating decimal ...

5 +11/12 -0.375 = 5.08333...(repeating 3)

If your calculator can convert this to a ratio of integers, you will get ...

= 61/12 = 5 1/12

You should recognize 0.375 as being the decimal equivalent of 3/8. Then the mixed-number arithmetic is ...

5 11/24 -3/8 = 5 11/24 -9/24 = 5 2/24 = 5 1/12

<em>Additional comment</em>

Many scientific and graphing calculators can do arithmetic with mixed numbers, and can convert between decimal and mixed-number formats. It might be worthwhile to get one. There are apps for phone and tablet that will do this, too.

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
