Suggestion from here is:

2 1/2 hours = 5 lots of half an hour so

910 / 5 = 182 miles per half hour

182 X 2 = 364 miles per hour


Or

910/5 =182 x 2 = 364


( sorry don't have a division sign on my keyboard)

Average speed = total distance/total time = 910/2.5

Dividing by 2.5 is a bit tricky so you could double numerator and denominator = 1820/5 = 364 mph
