Rima is traveling in her car at the speed of 60 km/hr. She drops her hat and didn’t recognize it for 10 minutes, during this time the hat travels due to air drag. As soon as she recognizes this she turns her car around and drive 50% faster to get her favourite hat, so that she could get her hat after 15 minutes after the fall. Find the average speed of the hat with which it travelled till it was caught.
