The distance between Sue and a dude ranch was 30 miles straight accross a rattlesnake-infested canyon. Instead of crossing the canyon, she hiked due north for a long time and then hiked due east for a ahorter leg of the journey to the ranch. If she averaged 4 mph and it took her 9 hours to get to the ranch, then how far did she hike in a northerly direction?
