Answer:
10.95 miles
Step-by-step explanation:

30% = 3/10
Number of hours you sleep = 24hours × 3/10
= 24hours ÷ 10 × 3

line given slope = x coefficient = 1/3
Perpendicular slopes must be opposite reciprocals of each other: m1 * m2 = –1
line slope (m) = -3
line equation formula = y = mx + b
y = -3x + b
from the point given
x = 3
y= 3
3 = -9 + b
b = 12
y = -3x + 12
