multiply by 4, equalling 80 quarter minutes
30 minutes
There are 30 minutes in half an hour and 15 minutes in a quarter of an hour
30 minutes = 1,800 seconds
Convert the minutes to seconds (multiply them by 60), then divide the result by 30. Alternately, you can first convert seconds to minutes, then divide the equivalents in minutes.

30 minutes since 1 quarter would be 15 minutes.
30 minutes Because half an hour is 30 minutes and If they say a quarter after 7 it means 7:15 and a quarter to 7 is 7:45
3 quarters of an hour is 45 minutes, 15 minutes would be one quarter and 30 mins would be two quarters.
Convert everything to a common unit (I suggest to convert to hours in this case, but minutes will do, too), then you can subtract.
Quarter 6 means for example... 4:30. the 6 in a clock is 30 minutes into an hour. So yeah
