Question

In a school, total school hours are divided as follows: 20 minutes for morning prayer, 20 minutes for recess and 8 periods each of 40 minutes duration. If the prayer time and recess time are increased to 40 minutes each, how long would each period be, assuming the number of school hours to be the same? ​

Answer 1

Answer:

When the prayer and recess time is increased to 40 minutes, each period would be 35 minutes long.

Step-by-step explanation:

Total school minutes= 20+20+(8×40)

                                  = 360 minutes

                                  = 6 hours

Total school minutes when prayer and recess time are increased to 40 minutes = 6 hours (given, that number of school hours would be the same)

Let the length of each period (in minutes) be 'p'.

So,

6 hours = 40 minutes +40 minutes +(8×p)

360 minutes = 80 minutes +8p

8p = 280 minutes

p = 280/8

p = 35 minutes

So, when the prayer and recess time is increased to 40 minutes, each period would be 35 minutes long.
