At 12 55, Neave left Town T for Town U, driving at a speed of 72 km/h. At 14 55, Henry also left Town T for Town U driving at a certain speed. Both of them did not change their speed throughout the journey. At 16 55, both of them passed a boutique that was 216 km away from Town U. How many minutes earlier did Henry reach Town U than Neave?

Distance that Neave travelled
= 4 x 72
= 288 km

Distance between Town T and Town U
= 288 + 216
= 504 km

Since Henry passed the boutique at the same time as Neave, it means that Henry travelled 288 km in 2 hours.

Henry's speed during the journey
= 288 ÷ 2
= 144 km/h

Duration that Henry took to reach Town U after passing the boutique
= 216 ÷ 144
= 1.5 h

Duration that Neave took to reach Town U after passing the boutique
= 216 ÷ 72
= 3 h

Difference between the time they took to reach Town U
= 3 - 1.5
= 1.5 h

1 h = 60 min
1.5 h = 1.5 x 60 = 90 min

Henry reached Town U 90 minutes earlier than Neave.

Answer(s): 90 min
