Sandy and Mary start at the same time at the top of Mt. Snowbird and hike down on different trails. They meet at the foot of the mountain two hours later. If Sandy hikes at an average speed of 3.75 mph and Mary's average rate is 2.25 mph, find the total number of miles they hiked.

hours x mph = miles
distance = speed * time
3.75 * 2 + 2.25 * 2
= 7.5 + 4.5 = 12 miles
