A person walks 1/3 mile in 1/9 hour. At what speed is the person walking in miles per hour?

ki77a [65]

Speed (v) could be determined using this following formula
v = distance ÷ time

plug in the numbers
v = $\frac{1}{3} : \frac{1}{9}$
v = $\frac{1}{3} \times \frac{9}{1}$
v = 9/3
v = 3

The speed is 3 miles per hour

$\displaystyle\\
15(2a - 2) = 5(a^2 -1) \\ \\ 
30a - 30 = 5a^2-5\\\\
-5a^2 + 30a -30 + 5 =0\\\\
-5a^2 + 30a -25 =0 ~~~~~\Big| \times (-1) \\\\
5a^2 - 30a +25 = 0~~~~~\Big| : 5 \\\\
a^2 - 6a +5 = 0 \\ \\ 
a_{12}= \frac{-b\pm \sqrt{b^2-4ac}}{2a}= \frac{6\pm \sqrt{36-20}}{2}= \frac{6\pm \sqrt{16}}{2}=\frac{6\pm 4}{2}= \boxed{3\pm 2} \\ \\ 
a_1 = 3+ 2 = \boxed{5}\\\\
a_2 = 3-2 = \boxed{1}$
