At 10 15, Andy left Town E for Town F, driving at a speed of 65 km/h. At 12 15, Howard also left Town E for Town F driving at a certain speed. Both of them did not change their speed throughout the journey. At 14 15, both of them passed a hypermart that was 195 km away from Town F. How many minutes earlier did Howard reach Town F than Andy?

Distance that Andy travelled
= 4 x 65
= 260 km

Distance between Town E and Town F
= 260 + 195
= 455 km

Since Howard passed the hypermart at the same time as Andy, it means that Howard travelled 260 km in 2 hours.

Howard's speed during the journey
= 260 ÷ 2
= 130 km/h

Duration that Howard took to reach Town F after passing the hypermart
= 195 ÷ 130
= 1.5 h

Duration that Andy took to reach Town F after passing the hypermart
= 195 ÷ 65
= 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

Howard reached Town F 90 minutes earlier than Andy.

Answer(s): 90 min
