Micah is watching a TV program that is 2 hours long during the program there are six commercials that are each 90 sec. How many

Sergeu [11.5K]

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

$90(6)=540\ sec$

Convert to minutes

Remember that

$1\ min=60\ sec$

$540\ sec=540/60=9\ min$

step 2

Subtract the duration of six commercials from the duration of the program

Remember that

$1\ h=60\ min$

$2\ h=2(60)=120\ min$

therefore

$120-9=111\ min$
