I left Work at 411 pm and was stopped by highway patrol 132

I left Work at 4:11 p.m. and was stopped by highway patrol 13.2 miles or 23 minutes later at 4:34 p.m. How fast was I traveling ?

13.2 miles/(23/60) hr = ~ 34.4 mph average

Cops don\'t stop you for average speed, but the speed they observe.
A car can go 90 mph for some time, then stop or slow down for a lower average.
