At 14 50, Ben left Town V for Town W, driving at a speed of 60 km/h. At 15 50, Gabriel also left Town V for Town W driving at a certain speed. Both of them did not change their speed throughout the journey. At 19 50, both of them passed a park that was 120 km away from Town W. How many minutes earlier did Gabriel reach Town W than Ben?

Distance that Ben travelled
= 5 x 60
= 300 km

Distance between Town V and Town W
= 300 + 120
= 420 km

Since Gabriel passed the park at the same time as Ben, it means that Gabriel travelled 300 km in 4 hours.

Gabriel's speed during the journey
= 300 ÷ 4
= 75 km/h

Duration that Gabriel took to reach Town W after passing the park
= 120 ÷ 75
= 1.6 h

Duration that Ben took to reach Town W after passing the park
= 120 ÷ 60
= 2 h

Difference between the time they took to reach Town W
= 2 - 1.6
= 0.4 h

1 h = 60 min
0.4 h = 0.4 x 60 = 24 min

Gabriel reached Town W 24 minutes earlier than Ben.

Answer(s): 24 min
