At 11 40, Tim left Town V for Town W, driving at a speed of 89 km/h. At 14 40, Jeremy also left Town V for Town W driving at a certain speed. Both of them did not change their speed throughout the journey. At 17 40, both of them passed a farm that was 267 km away from Town W. How many minutes earlier did Jeremy reach Town W than Tim?
Duration that Tim travelled from 11 40 to 17 40 = 6 h
Distance that Tim travelled
= 6 x 89
= 534 km
Distance between Town V and Town W
= 534 + 267
= 801 km
Since Jeremy passed the farm at the same time as Tim, it means that Jeremy travelled 534 km in 3 hours.
Jeremy's speed during the journey
= 534 ÷ 3
= 178 km/h
Duration that Jeremy took to reach Town W after passing the farm
= 267 ÷ 178
= 1.5 h
Duration that Tim took to reach Town W after passing the farm
= 267 ÷ 89
= 3 h
Difference between the time they took to reach Town W
= 3 - 1.5
= 1.5 h
1 h = 60 min
1.5 h = 1.5 x 60 = 90 min
Jeremy reached Town W 90 minutes earlier than Tim.
Answer(s): 90 min
