Write a word problem whose solution is |20|=20

Garry decided to bike from his house to his new friend Jerry's house at a rate of 15 miles per hour. Jerry's house is only 10 miles away, but Garry got distracted and rode for 2 hours, passing by Jerry's house by accident. If Garry rode on a number line with each interval equal to 1mile (his house at 0), passing Jerry's house (his house at 10), and stopped after 2 hours after his realization, how many miles away is Garry from Jerry's house?
