As a former Victorian now living in the US, I think it's apt to point out that 46 degrees Celsius is 114.8 degrees Fahrenheit and 70 kilometers is 43.495 miles.
Unless you really think the police were being precise to within a meter (Google says .001 mile =~ 1.6 meters), it's "about 115F" and "about 40 miles", respectively. (Got a bit unlucky on the miles, I'd also consider "about 45".)
