Answer:
80 minutes
Step-by-step explanation:
We can solve this problem using rule of three:
The ratio of number of minutes and number of miles is 24 to 3, that is, for each 24 minutes running, she runs 3 miles.
So, if to run 3 miles she needs 24 minutes, to run 10 miles, how much time she will need:
3 miles -> 24 minutes
10 miles -> X minutes
3/10 = 24/X
X = 10 * 24 / 3 = 80 minutes.
She will take 80 minutes to run 10 miles.

Answer:
5x + 2y = 9
Step-by-step explanation:
Find the slope of the line that is perpendicular to 2x - 5y = 7 :
m= 
Find the y - intercept of the function:
b = 
substitute m=
and b =
into y = mx + b :
y =
+ 
y = 5x + 2y = 9
