So lets start with scenario 2....... Let, they meet at point X on the route....... also they save 20 minutes...... so the time it would take to go from point X to station and come back to point X by car is 20 minutes..... so wife needs 10 minutes to go from point X (where they met) to station.........Now, he arrives 1 hour early...... So there is 1 hour left till wife arrives at the station...... He starts walking immediately after reaching station on the same route...... So when he starts walking, his wife is 60 minutes away from station...... And when they meet at point X , his wife is 10 minutes away from station...... So during his walk, his wife drove for 50 minutes..... In other words...... He walked for 50 minutes......😭🥀💔
