At 11 25, Fred left Town E for Town F, driving at a speed of 60 km/h. At 14 25, Glen also left Town E for Town F driving at a certain speed. Both of them did not change their speed throughout the journey. At 16 25, both of them passed a bakery that was 180 km away from Town F. How many minutes earlier did Glen reach Town F than Fred?
Duration that Fred travelled from 11 25 to 16 25 = 5 h
Distance that Fred travelled
= 5 x 60
= 300 km
Distance between Town E and Town F
= 300 + 180
= 480 km
Since Glen passed the bakery at the same time as Fred, it means that Glen travelled 300 km in 2 hours.
Glen's speed during the journey
= 300 ÷ 2
= 150 km/h
Duration that Glen took to reach Town F after passing the bakery
= 180 ÷ 150
= 1.2 h
Duration that Fred took to reach Town F after passing the bakery
= 180 ÷ 60
= 3 h
Difference between the time they took to reach Town F
= 3 - 1.2
= 1.8 h
1 h = 60 min
1.8 h = 1.8 x 60 = 108 min
Glen reached Town F 108 minutes earlier than Fred.
Answer(s): 108 min
