At 10 30, Oliver left Town F for Town G, driving at a speed of 96 km/h. At 12 30, Flynn also left Town F for Town G driving at a certain speed. Both of them did not change their speed throughout the journey. At 15 30, both of them passed a bakery that was 192 km away from Town G. How many minutes earlier did Flynn reach Town G than Oliver?

Distance that Oliver travelled
= 5 x 96
= 480 km

Distance between Town F and Town G
= 480 + 192
= 672 km

Since Flynn passed the bakery at the same time as Oliver, it means that Flynn travelled 480 km in 3 hours.

Flynn's speed during the journey
= 480 ÷ 3
= 160 km/h

Duration that Flynn took to reach Town G after passing the bakery
= 192 ÷ 160
= 1.2 h

Duration that Oliver took to reach Town G after passing the bakery
= 192 ÷ 96
= 2 h

Difference between the time they took to reach Town G
= 2 - 1.2
= 0.8 h

1 h = 60 min
0.8 h = 0.8 x 60 = 48 min

Flynn reached Town G 48 minutes earlier than Oliver.

Answer(s): 48 min
