At 11 50, Cole left Town L for Town M, driving at a speed of 74 km/h. At 13 50, Wesley also left Town L for Town M driving at a certain speed. Both of them did not change their speed throughout the journey. At 15 50, both of them passed a museum that was 222 km away from Town M. How many minutes earlier did Wesley reach Town M than Cole?

Distance that Cole travelled
= 4 x 74
= 296 km

Distance between Town L and Town M
= 296 + 222
= 518 km

Since Wesley passed the museum at the same time as Cole, it means that Wesley travelled 296 km in 2 hours.

Wesley's speed during the journey
= 296 ÷ 2
= 148 km/h

Duration that Wesley took to reach Town M after passing the museum
= 222 ÷ 148
= 1.5 h

Duration that Cole took to reach Town M after passing the museum
= 222 ÷ 74
= 3 h

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

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

Wesley reached Town M 90 minutes earlier than Cole.

Answer(s): 90 min
