Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Malcolm is trying to find the fastest walk to school and is currently comparing two routes. In the first route, he walks for 6 minutes uphill, walks for twice this amount of time along a path, then finishes the journey in a third of the time it took to walk the first two stages. In the second route, he walks along a flat path for 14 minutes, then finishes the walk in twice this amount of time. In minutes, how much longer was the second route compared with the first?

### Response:
In the first route, Malcolm spends 6 minutes * 2 = <<6*2=12>>12 minutes walking along the path.
So the first two stages of this route take him 6 + 12 = <<6+12=18>>18 minutes.
He then spends 18 / 3 = <<18/3=6>>6 minutes walking to school.
Thus, the first route takes him a total of 18 + 6 = <<24=24>>24 minutes.
In the second route, the second stage takes him 14 * 2 = <<14*2=28>>28 minutes.
So the second route takes a total of 28 + 14 = <<28+14=42>>42 minutes.
Hence, the second route takes an extra 42 minutes for the second route – 24 minutes for the first route = <<42-24=18>>18 minutes.
