At 11 20, Jack left Town D for Town E, driving at a speed of 67 km/h. At 14 20, Jeremy also left Town D for Town E driving at a certain speed. Both of them did not change their speed throughout the journey. At 17 20, both of them passed a mosque that was 201 km away from Town E. How many minutes earlier did Jeremy reach Town E than Jack?

Distance that Jack travelled
= 6 x 67
= 402 km

Distance between Town D and Town E
= 402 + 201
= 603 km

Since Jeremy passed the mosque at the same time as Jack, it means that Jeremy travelled 402 km in 3 hours.

Jeremy's speed during the journey
= 402 ÷ 3
= 134 km/h

Duration that Jeremy took to reach Town E after passing the mosque
= 201 ÷ 134
= 1.5 h

Duration that Jack took to reach Town E after passing the mosque
= 201 ÷ 67
= 3 h

Difference between the time they took to reach Town E
= 3 - 1.5
= 1.5 h

1 h = 60 min
1.5 h = 1.5 x 60 = 90 min

Jeremy reached Town E 90 minutes earlier than Jack.

Answer(s): 90 min
