At 10 35, Cody left Town U for Town V, driving at a speed of 64 km/h. At 13 35, Tommy 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 35, both of them passed a park that was 256 km away from Town V. How many minutes earlier did Tommy reach Town V than Cody?

Distance that Cody travelled
= 5 x 64
= 320 km

Distance between Town U and Town V
= 320 + 256
= 576 km

Since Tommy passed the park at the same time as Cody, it means that Tommy travelled 320 km in 2 hours.

Tommy's speed during the journey
= 320 ÷ 2
= 160 km/h

Duration that Tommy took to reach Town V after passing the park
= 256 ÷ 160
= 1.6 h

Duration that Cody took to reach Town V after passing the park
= 256 ÷ 64
= 4 h

Difference between the time they took to reach Town V
= 4 - 1.6
= 2.4 h

1 h = 60 min
2.4 h = 2.4 x 60 = 144 min

Tommy reached Town V 144 minutes earlier than Cody.

Answer(s): 144 min
