Total school hours = morning prayer time + recess time + time of total periods
Total school hours = 20 + 20 + ( 8 x 40 )
Total school hours = 40 + 320
Total school hours = 360
Now if the prayer time and recess time are increased to 40 minutes, and since
Total school hours = morning prayer time + recess time + time of total periods
Total school hours = 40 + 40 + ( 8 x X )
360 = 40 + 40 + ( 8 x X )
280 = 8 x X
X = 35 min
Hence if the prayer time and recess time are increased to 40 minutes then the time of the periods will be 35 min.
Total school hours = 20 + 20 + ( 8 x 40 )
Total school hours = 40 + 320
Total school hours = 360
Now if the prayer time and recess time are increased to 40 minutes, and since
Total school hours = morning prayer time + recess time + time of total periods
Total school hours = 40 + 40 + ( 8 x X )
360 = 40 + 40 + ( 8 x X )
280 = 8 x X
X = 35 min
Hence if the prayer time and recess time are increased to 40 minutes then the time of the periods will be 35 min.
