Answer:
111 minutes
Step-by-step explanation:
step 1
Find out how long are the six commercial
Multiply the number of commercials by 90 seconds
so
[tex]90(6)=540\ sec[/tex]
Convert to minutes
Remember that
[tex]1\ min=60\ sec[/tex]
[tex]540\ sec=540/60=9\ min[/tex]
step 2
Subtract the duration of six commercials from the duration of the program
Remember that
[tex]1\ h=60\ min[/tex]
so
[tex]2\ h=2(60)=120\ min[/tex]
therefore
[tex]120-9=111\ min[/tex]
