Question

If the total rainfall recorded for the month of August was 930 mm, find the average daily rainfall

Answer 1

the formula for finding average = sum of all terms/ number of terms
Sum of terms = 930mm.
Number of terms = number of das in August = 31 days
Average daily rainfall = 930/31 = 30mm

Answer 2

$since \: total \: days \: in \: the \: month \: of \: august = 31 \\ \\ therefore \\ \\ average \: daily \: rain fall \: in \: this \: month \\ \\ = \frac{930}{31} = 30 \: mm$
