A commuting student leaves home and drives to school at an average speed of 38.0 km/h. After 25.0 min he realizes that he has forgotten his homework and returns home to get it at the same average speed. It takes 10.0 min to discover the report, after which the trip to school 38.0 km away to the east is resumed at the same speed as before.
