Ashley drove 648 miles in 9 hours. At the same rate, how many miles would she drive in 7 hours?

kvv77 [185]

First, divide 648 by 9. 648/9=72. Now we know that Ashley covers 72 miles in an hour. In order to get the number of miles she covers in 7 hours we must multiply 72 by 7 which equals 504. So Ashley would drive 504 miles in 7 hours.

$d = 4n -2 \\d + 2 = 4n\\\frac{1}{4}d + \frac{2}{4} = n\\\\n = 0.25d + 0.5$

For a 3-penny nail
$n = 0.25d + 0.5\\ n = 0.25(3) + 0.5\\n = 0.75 +0.5\\\\n = 1.25$

For a 6-penny nail
$n = 0.25d + 0.5\\n = 0.25(6) + 0.5\\n = 1.5 + 0.5\\\\n = 2$

For a 10-penny nail
$n = 0.25d + 0.5\\n = 0.25(10) + 0.5\\n = 2.5 + 0.5\\\\n = 3$

Hope that helped :)
