At 10 25, Jenson left Town S for Town T, driving at a speed of 64 km/h. At 13 25, Julian also left Town S for Town T driving at a certain speed. Both of them did not change their speed throughout the journey. At 15 25, both of them passed a farm that was 192 km away from Town T. How many minutes earlier did Julian reach Town T than Jenson?

Distance that Jenson travelled
= 5 x 64
= 320 km

Distance between Town S and Town T
= 320 + 192
= 512 km

Since Julian passed the farm at the same time as Jenson, it means that Julian travelled 320 km in 2 hours.

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

Duration that Julian took to reach Town T after passing the farm
= 192 ÷ 160
= 1.2 h

Duration that Jenson took to reach Town T after passing the farm
= 192 ÷ 64
= 3 h

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

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

Julian reached Town T 108 minutes earlier than Jenson.

Answer(s): 108 min
