Question 18
At Gabriel's house they are very methodical. Every business day the mother leaves on her motorcycle at the same time, at the same speed and along the same path to pick up Gabriel from school. He arrives at school at exactly 12 o'clock and immediately returns home with Gabriel, along the same path and at the same speed. Of course, they arrive home at exactly the same time every day.
One day, Gabriel left school early, and at 11 hours and 15 minutes he began the walk home. On the way he met his mother, who was picking him up from school, like every day. As soon as they met, they immediately returned to the house, arriving 20 minutes earlier than usual.
Determine how many minutes earlier than usual they would have arrived home if Gabriel began the walk at 11 hours and 33 minutes.
