A typical 60-minute TV program
has about 16 minutes of
commercials. How many minutes
of commercials are shown in a 90
minute TV program?

Step-by-step explanation:

Well 90 is only 30 more than 60 which is half of sixty.

so divide 60 by 2 to get 30 and divide 16 by 2 and get 8.

then add 30 to 60 to get 90 and add 8 to 16 to get 24.

ans. 24 minutes of commercials

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

im guessing (23,14). hope this : )
