Question

A school has 8 periods in a day each of 45 minutes duration. How long would each period be, if the school has 9 periods a day,assuming the number of school hours to be the same. ​

Answer 1

Answer:

40 minutes

Step-by-step explanation:

let the duration of each period, when there are 9 periods a day in the school be X minutes

45 * 8 = X * 9

X = 45*8 / 9 = 40

hence, in this case, the duration of each period will be 40 minutes.
