Answer:
(a) ![X(t)=X(0)+\Delta X*t=5-0.5*t](https://tex.z-dn.net/?f=X%28t%29%3DX%280%29%2B%5CDelta%20X%2At%3D5-0.5%2At)
(b) ![X(t)=X(0)+\Delta X*t=1+0.5*t](https://tex.z-dn.net/?f=X%28t%29%3DX%280%29%2B%5CDelta%20X%2At%3D1%2B0.5%2At)
(c) At 4 weeks, when both will be seeing an average of 3 hours of TV.
Step-by-step explanation:
a) For the students, they start at X(0)=5 h and ΔX=-0.5 h/week.
We can write
![X(t)=X(0)+\Delta X*t=5-0.5*t](https://tex.z-dn.net/?f=X%28t%29%3DX%280%29%2B%5CDelta%20X%2At%3D5-0.5%2At)
b) For the professors, they start at X(0)=1 h and ΔX=+0.5 h/week.
We can write
![X(t)=X(0)+\Delta X*t=1+0.5*t](https://tex.z-dn.net/?f=X%28t%29%3DX%280%29%2B%5CDelta%20X%2At%3D1%2B0.5%2At)
c) The seew which they will be watching the same amount of hours will be the 4th week.
![X(t)=5-0.5*t=1+0.5*t\\\\5-1=(0.5+0.5)*t\\\\t=4\, weeks](https://tex.z-dn.net/?f=X%28t%29%3D5-0.5%2At%3D1%2B0.5%2At%5C%5C%5C%5C5-1%3D%280.5%2B0.5%29%2At%5C%5C%5C%5Ct%3D4%5C%2C%20weeks)
The amount of hours will be
![x(4)=1+0.5*4=1+2=3\,hours](https://tex.z-dn.net/?f=x%284%29%3D1%2B0.5%2A4%3D1%2B2%3D3%5C%2Chours)
