3. A correspondent rides a bicycle and asks to deliver the letter to a certain place within the specified time, if it is 15km per hour. He can arrive 24 minutes early. If he drives at the speed of 12 km per hour, he will be 15 minutes late. What was the initial time? How long is his journey to a place?

Solution: Let the distance be xkm.

X = 39km km

Original time: 3915+24/60 = 3 hours.
