At 10 45, Ryan left Town U for Town V, driving at a speed of 60 km/h. At 13 45, Andy also left Town U for Town V driving at a certain speed. Both of them did not change their speed throughout the journey. At 15 45, both of them passed a boutique that was 180 km away from Town V. How many minutes earlier did Andy reach Town V than Ryan?

Distance that Ryan travelled
= 5 x 60
= 300 km

Distance between Town U and Town V
= 300 + 180
= 480 km

Since Andy passed the boutique at the same time as Ryan, it means that Andy travelled 300 km in 2 hours.

Andy's speed during the journey
= 300 ÷ 2
= 150 km/h

Duration that Andy took to reach Town V after passing the boutique
= 180 ÷ 150
= 1.2 h

Duration that Ryan took to reach Town V after passing the boutique
= 180 ÷ 60
= 3 h

Difference between the time they took to reach Town V
= 3 - 1.2
= 1.8 h

1 h = 60 min
1.8 h = 1.8 x 60 = 108 min

Andy reached Town V 108 minutes earlier than Ryan.

Answer(s): 108 min
