Hi i don't understand why we have to multiply 10 not 20 for 'number of miles per trip' in below equation. In exhibit 1, average miles per route is 20 right? Cost per trip = (Depreciation per mile + fuel per mile) * number of miles per trip + insurance cost per trip + labour cost Cost per trip = (420k / 300k + 0.5) * 10 + 10,500 / 350 / 10 + 20 * 1 = £61

Hi i don't understand why we have to multiply 10 not 20 for 'number of miles per trip' in below equation.

In exhibit 1, average miles per route is 20 right?

Cost per trip = (Depreciation per mile + fuel per mile) * number of miles per trip + insurance cost per trip + labour cost
Cost per trip = (420k / 300k + 0.5) * 10 + 10,500 / 350 / 10 + 20 * 1 = £61

Hi there,

I'm a bit confused by your question. It looks like you do multiply by 10 (see image below).

Hi there! I'd also like to know why we multiply by 10 and not by 20? The average miles per trip is 20 right?
