Julia's internet speed is 20 MBps (megabytes per second). How many songs she can download in half an hour if the size per song is 5MB?
How many minutes are in half an hour? ** 1 hour has 60 minutes, therefore 1/2 hour has 1/2*60 = <<1/2*60=30>>30 minutes
How many seconds are in half an hour? ** 1 minute has 60 seconds, therefore 30 minutes has 30*60 = <<1800=1800>>1800 seconds
How many seconds does it take to download one song? ** If Julia's internet speed is 20MBps and each song has a size of 5MB, then it would take 5/20=1/4 seconds to download one song
How many songs could Julia download in half an hour? ** If it takes 1/4 seconds to download 1 song, then in 1800 seconds, Julia could download 1800/(1/4) = 1800 * 4 = 7200 songs
