Answer 1

Answer:

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.
