At 11 25, Cody left Town V for Town W, driving at a speed of 61 km/h. At 13 25, Archie also left Town V for Town W driving at a certain speed. Both of them did not change their speed throughout the journey. At 15 25, both of them passed a bakery that was 183 km away from Town W. How many minutes earlier did Archie reach Town W than Cody?
Duration that Cody travelled from 11 25 to 15 25 = 4 h
Distance that Cody travelled
= 4 x 61
= 244 km
Distance between Town V and Town W
= 244 + 183
= 427 km
Since Archie passed the bakery at the same time as Cody, it means that Archie travelled 244 km in 2 hours.
Archie's speed during the journey
= 244 ÷ 2
= 122 km/h
Duration that Archie took to reach Town W after passing the bakery
= 183 ÷ 122
= 1.5 h
Duration that Cody took to reach Town W after passing the bakery
= 183 ÷ 61
= 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
Archie reached Town W 90 minutes earlier than Cody.
Answer(s): 90 min
