Antonio trained totally 780 minutes in the week. In order to calculate the total number of hours Antonio has trained, we should divide the number of minutes with the number of minutes in one hour (60) : 780/60=12

An order of magnitude is an approximate measure of the size of a number. It is equal to the logarithm (base 10) rounded to a whole number.

12=1.2*10^2
