At 11 25, Owen left Town G for Town H, driving at a speed of 89 km/h. At 14 25, Vincent also left Town G for Town H driving at a certain speed. Both of them did not change their speed throughout the journey. At 17 25, both of them passed a market that was 267 km away from Town H. How many minutes earlier did Vincent reach Town H than Owen?

Distance that Owen travelled
= 6 x 89
= 534 km

Distance between Town G and Town H
= 534 + 267
= 801 km

Since Vincent passed the market at the same time as Owen, it means that Vincent travelled 534 km in 3 hours.

Vincent's speed during the journey
= 534 ÷ 3
= 178 km/h

Duration that Vincent took to reach Town H after passing the market
= 267 ÷ 178
= 1.5 h

Duration that Owen took to reach Town H after passing the market
= 267 ÷ 89
= 3 h

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

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

Vincent reached Town H 90 minutes earlier than Owen.

Answer(s): 90 min
