Average truck spd 100mph?!

Looking at a used 2021 f150 imported from Canada. 11800 miles engine hours 219 idle hours 109. Doing the math...
miles/(engine hours-idle hours)= 11800/(219-109)= 107 mph!?!?!?!? That's obviously not correct. But the equation makes sense to me
other way to do it is miles/total engine hours =11800/219=54 mph. This is more reasonable but the equation doesn't make as much sense to me.

If I know the truck was only moving for 109 hours how did it go 11800 miles?! What am I missing here. I've seen the equation done both ways. Trying to make sure there isn't something fishy going on.

Yup I agree. Can we say that the truck is not movong when it is accumulating idle hours? If this is the case, it went 11800 miles in 109 hours (total-idle) .

I guess you could say they are both average speeds but they measure different things. One is average speed over the time it was running, and the other is average speed when the truck was actually moving.

Is it possible they are displaying KPH? Which would throw your number off a bit

I'm using engine hours and idle hours. No distance measurement there.
Odometer units are in miles.
But im not saying its impossible

The total engine hours are 219. That's your number.
