Question

A school has 8 periods in a day such that each period is of $35minutes$. If the number of periods is reduced to 7, then how long would each period be?

Answer 1

Find the time of period:

Time for $1$ period = $35minutes$

Number of periods in a day = $8$

Total time for $8$ periods = $8\times 35=280minutes$

Now, number of periods in a day = $7$

New time for each period = $\frac{280}{7}=40minutes$

Hence, each period will be $40minutes$.
