In an election, there are a total of 80000 voters and there are two candidates, X and Y. 80 % of the voters go for polls out of

Sergio [31]

Well, from 80000 only 80% went to the polls, how many is that?

if we take 80000 to be the 100%, then how much is the 80%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
80000&100\\
x&80
\end{array}\implies \cfrac{80000}{x}=\cfrac{100}{80}\implies \cfrac{80000\cdot 80}{100}\implies 64000=x$

now, from those 64000 60% voted for X, that means that the remaining 40% voted for Y, how many is that 40%?

well, if we take 64000 to be 100%, how much is 40%?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
64000&100\\ y&40
\end{array}\implies \cfrac{64000}{y}=\cfrac{100}{40}\implies \cfrac{64000\cdot 40}{100}=y$

Two automobiles start together from the same place and travel along the same route. The first averages 40 miles per hour and the

zheka24 [161]

Answer:

the second car is 75 miles longer than the first car for 5 hours

Step-by-step explanation:

First we need to know the distance each one traveled in 5 hours

the first one travels 40 miles in one hour

1 h = 40 mi

1h * 5 = 40mi * 5

5h = 200 mi

the second one travels 55 miles in one hour

1 h = 55 mi

1h * 5 = 55mi * 5

5h = 275 mi

so the first one traveled 200 miles and the second 275 miles

if 275 we have 200 left, we will get how many more miles the second car made in 5 hours

275mi - 200mi = 75mi
