At 11 55, Julian left Town V for Town W, driving at a speed of 67 km/h. At 14 55, Daniel 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 55, both of them passed a museum that was 201 km away from Town W. How many minutes earlier did Daniel reach Town W than Julian?
Duration that Julian travelled from 11 55 to 17 55 = 6 h
Distance that Julian travelled
= 6 x 67
= 402 km
Distance between Town V and Town W
= 402 + 201
= 603 km
Since Daniel passed the museum at the same time as Julian, it means that Daniel travelled 402 km in 3 hours.
Daniel's speed during the journey
= 402 ÷ 3
= 134 km/h
Duration that Daniel took to reach Town W after passing the museum
= 201 ÷ 134
= 1.5 h
Duration that Julian took to reach Town W after passing the museum
= 201 ÷ 67
= 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
Daniel reached Town W 90 minutes earlier than Julian.
Answer(s): 90 min
