What is a time/km charge on a car rental?

Question

I am looking to rent a car in Panama City, Panama via Thrifty. I went to their website, panamathrifty.com, and put in the desired information (mid sized car, start/end dates, etc...) and was delivered to a screen describing the total cost. I have attached a picture here. My main question is what is the Time/km charge? It seems like a rate, and yet it is directly added (only once) to the total. What does this mean? Time/distance = $? It would make sense to me if this were something like a $/km (though if this were the case I'd expect the value to be something like $0.20/km... not $6/km) but it does not appear to be the case. I tried calling customer service and they told me that there is unlimited miles on the rentals in this area (as there normally is), so I am clueless

Answer 1

I don't know for certain, but I would guess that the "time/km" entry actually means "time or km" (rather than "time per km", which doesn't make sense). You are doing a time-based rental (because you have unlimited km), which is 6 days, at presumably $1 per day. That seems rather inexpensive, but as mentioned in the comments it may be normal for cars in that area.
