Use the following scenario to answer the question below:

Antonio recorded the number of minutes he rode his bicycle each day leading up to his race. He knew he totalled 780 minutes for the week. After the race, he filled out a survey listing the total number of hours he had trained the last week.

What is the Order of Magnitude of the number of hours he trained?
a. 1
b.2
c.3
d.4

Respuesta :

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
