ronaldo delivers the papers at the rate of 6 papers in 24 minutes. how much longer would it take him to deliver 56 papers than 4

UkoKoshka [18]

We are given

Ronaldo delivers the papers at the rate of 6 papers in 24 minutes

so, number of papers =6 in time =24 minutes

so, firstly we can find rate

rate = ( number of papers)/( time taken)

$r=\frac{6}{24} =\frac{1}{4}$

now, we can find times

Time for 56 papers:

we are given

number of papers =56

rate is

$r=\frac{1}{4}$

now, we can find time

$t_1=\frac{56}{r}$

$t_1=\frac{56}{\frac{1}{4}}$

$t_1=224min$

Time for 41 papers:

we are given

number of papers =41

rate is

$r=\frac{1}{4}$

now, we can find time

$t_2=\frac{41}{r}$

$t_2=\frac{41}{\frac{1}{4}}$

$t_2=164min$

now, we can find time difference

$t=t_1-t_2$

so, we can plug values

$t=224-164$

$t=60 min$ ..............Answer

Hence, write as single<br> frachon in its lowest terms.<br> 2/y-1 - 4/y^2-1

sleet_krkn [62]

Answer:

$\frac{2}{y+1}$

Step-by-step explanation:

Factorise the denominator of the second fraction

y² - 1 = (y - 1)(y + 1) ← difference of squares

To obtain a common denominator

multiply numerator/ denominator of first fraction by (y + 1)

= $\frac{2(y+1)}{(y-1)(y+1)}$ - $\frac{4}{(y-1)(y+1)}$ ← subtract numerators leaving the common denominator

= $\frac{2y+2-4}{(y-1)(y+1)}$

= $\frac{2y-2}{(y-1)(y+1)}$

= $\frac{2(y-1)}{(y-1)(y+1)}$ ← cancel common factor (y - 1) on numerator/denominator

= $\frac{2}{y+1}$
