At 10 55, Perry left Town G for Town H, driving at a speed of 62 km/h. At 13 55, Daniel also left Town G for Town H driving at a certain speed. Both of them did not change their speed throughout the journey. At 15 55, both of them passed a temple that was 248 km away from Town H. How many minutes earlier did Daniel reach Town H than Perry?
Duration that Perry travelled from 10 55 to 15 55 = 5 h
Distance that Perry travelled
= 5 x 62
= 310 km
Distance between Town G and Town H
= 310 + 248
= 558 km
Since Daniel passed the temple at the same time as Perry, it means that Daniel travelled 310 km in 2 hours.
Daniel's speed during the journey
= 310 ÷ 2
= 155 km/h
Duration that Daniel took to reach Town H after passing the temple
= 248 ÷ 155
= 1.6 h
Duration that Perry took to reach Town H after passing the temple
= 248 ÷ 62
= 4 h
Difference between the time they took to reach Town H
= 4 - 1.6
= 2.4 h
1 h = 60 min
2.4 h = 2.4 x 60 = 144 min
Daniel reached Town H 144 minutes earlier than Perry.
Answer(s): 144 min
