Answer:
<h2>1:58 minutes after the show</h2>
Step-by-step explanation:
Step one:;
given data
start time= 7:00 am
end time= 9:00 am
we are told that one broadcast shows commercial every 17minutes
and the other shows commercials every 14 minutes
now the time when they both sho commercial is given by the greates common multiple of the times 17 and 14
multiples of 17= 17,34,51,68,85,102,119,136,153,170,187,204,221,238
multiples of 14= 14,28,42,56,70,84,98,112,126,140,154,168,182,196,210,224,238
for the number above 238 is common to both
238minutes to hours= 3.96667
=3:58 minutes
this shows that commercials will show at the same time 1:58 minutes after the show
