At 11 55, Tim left Town J for Town K, driving at a speed of 62 km/h. At 14 55, Warren also left Town J for Town K driving at a certain speed. Both of them did not change their speed throughout the journey. At 16 55, both of them passed a cinema that was 248 km away from Town K. How many minutes earlier did Warren reach Town K than Tim?

Distance that Tim travelled
= 5 x 62
= 310 km

Distance between Town J and Town K
= 310 + 248
= 558 km

Since Warren passed the cinema at the same time as Tim, it means that Warren travelled 310 km in 2 hours.

Warren's speed during the journey
= 310 ÷ 2
= 155 km/h

Duration that Warren took to reach Town K after passing the cinema
= 248 ÷ 155
= 1.6 h

Duration that Tim took to reach Town K after passing the cinema
= 248 ÷ 62
= 4 h

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

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

Warren reached Town K 144 minutes earlier than Tim.

Answer(s): 144 min
