If you would like to know Tom's average rate of jogging, you can calculate this using the following steps:
10:30 a.m. - 12:15 p.m. ... 1 hour 45 minutes = 105 minutes
7 miles ... 105 minutes
x miles = ? ... 60 minutes = 1 hour
7 * 60 = 105 * x
x = 7 * 60 / 105
x = 4 miles per hour
Tom's average rate of jogging was 4 miles per hour.
