Final answer:
Approximately 0.35 40-second commercials can be run in 1 hour. A television station with 14 minutes of advertising per hour can run 21 of the 40-second (or 2/3-minute) commercials.
Step-by-step explanation:
To find the number of 40-second commercials that can be run in 1 hour, we need to convert both the advertising time and the commercial time to the same unit. Since there are 60 minutes in 1 hour, the 14 minutes of advertising is equivalent to (14/60) hours. Similarly, 40 seconds is equivalent to (40/60) minutes, which is (40/60)*(1/60) hours.
To find the number of commercials, we can divide the total advertising time by the time it takes to run one commercial:
(14/60)/(40/60)*(1/60) = (14/60)*(60/40) = 14/40 = 0.35 commercials.
Therefore, approximately 0.35 40-second commercials can be run in 1 hour.
A television station with 14 minutes of advertising per hour can run 21 of the 40-second (or 2/3-minute) commercials.
We need to calculate how many 40-second commercials can be run in 14 minutes of advertising time. First, we convert 40 seconds to minutes by dividing by 60, since there are 60 seconds in a minute. This gives us ⅓ minute, or approximately 0.6667 minutes per commercial.
Now, we take the total advertising time available, which is 14 minutes, and divide it by the length of one commercial:
14 minutes ÷ 0.6667 minutes per commercial = 21 commercials
Therefore, a television station can run 21 of these 40-second (⅓-minute) commercials in one hour.
