Jason rides his bike home from school 2 miles. On his way back home from school, he passes his house to go to his friend's house, which is a mile farther. What is the total distance Jason traveled from school?

The distance Jason traveled from school is 2 miles + 1 mile = <<2+1=3>>3 miles. Answer: \boxed{3}.

To find the total distance Jason traveled from school, we need to add the distance he traveled to his friend's house (1 mile) to the distance from school to his house (2 miles).

The total distance Jason traveled from school is 2 miles + 1 mile = 3 miles.
