I think it would be 2 and a half hours/ 2 hours and 30 minutes.
M = - 3 + 9 / 6 + 4
m = 6 / 10
m = 3/5
- 3 = 3/5 ( 6 ) + c
- 15 = 18 + 5c
5c = - 33
c = - 33/5
y = 3/5x - 33/5

Step-by-step explanation:
Since a hexagon has 6 interior angles and the measure of one is 120°, then
sum of interior angles = 6 × 120° = 720°
exterior angle = 180° - interior angle = 180° - 120° = 60°
Distribute to eliminate the parenthesis
x^2 + 2x + 6x + 12 = 60
Combine like terms
x^2 + 8x + 12 = 60
Subtract 60 from both sides
x^2 + 8x - 48 = 0
Factor the equation
(x+12)(x-4)=0
x+12=0
x+4=0
x= -12 and -4
