At 14 55, Charlie left Town E for Town F, driving at a speed of 73 km/h. At 16 55, Zane also left Town E for Town F driving at a certain speed. Both of them did not change their speed throughout the journey. At 18 55, both of them passed a florist that was 219 km away from Town F. How many minutes earlier did Zane reach Town F than Charlie?

Distance that Charlie travelled
= 4 x 73
= 292 km

Distance between Town E and Town F
= 292 + 219
= 511 km

Since Zane passed the florist at the same time as Charlie, it means that Zane travelled 292 km in 2 hours.

Zane's speed during the journey
= 292 ÷ 2
= 146 km/h

Duration that Zane took to reach Town F after passing the florist
= 219 ÷ 146
= 1.5 h

Duration that Charlie took to reach Town F after passing the florist
= 219 ÷ 73
= 3 h

Difference between the time they took to reach Town F
= 3 - 1.5
= 1.5 h

1 h = 60 min
1.5 h = 1.5 x 60 = 90 min

Zane reached Town F 90 minutes earlier than Charlie.

Answer(s): 90 min
