At 14 30, Albert left Town T for Town U, driving at a speed of 96 km/h. At 16 30, Ahmad also left Town T for Town U driving at a certain speed. Both of them did not change their speed throughout the journey. At 19 30, both of them passed a farm that was 192 km away from Town U. How many minutes earlier did Ahmad reach Town U than Albert?

Distance that Albert travelled
= 5 x 96
= 480 km

Distance between Town T and Town U
= 480 + 192
= 672 km

Since Ahmad passed the farm at the same time as Albert, it means that Ahmad travelled 480 km in 3 hours.

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

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

Duration that Albert took to reach Town U after passing the farm
= 192 ÷ 96
= 2 h

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

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

Ahmad reached Town U 48 minutes earlier than Albert.

Answer(s): 48 min
