Also, the hire was only 2 days and around 18 hours - from late afternoon on day 1 to late-morning on day 3, so @frauenfelder’s calculations re average speed are probably off. He also did notice that the receipt was in km (and converted the total distance back to mlles for USian readers) but failed to point out that the odometer readings he repeated were actually the km readings.
(Things like this are how spacecraft crash!)
TBH I would believe her mileage estimate. Even 946 km is nearly 600 miles, which seems unlikely for what is really in two days’ usage unless she was driving late into the nights and early hours. Equally likely, this was entered on a screen where numbers for two different vehicles were transposed. Someone else may also have a problem (or came out ahead).
