Answer:

308 minutes

Explanation:

The average waiting time = [tex]\frac{42*5^2+4(540)^2}{2*(480-(42*5)-540*4))}[/tex]

= [tex]\frac{42*25+1166400}{2*(480-(210)-2160))}[/tex]

= [tex]\frac{1167450}{-3780}[/tex]

= - 308.85 minutes

Thus; alex average waiting​ time, in​ minutes,  308 minutes  if he still wants to  continues to be the only​ worker.
