Diana drove 169.5 miles in total.

Step-by-step explanation:

Average speed first = 50 miles

Driving time = 1.5 hours

Distance = Speed*Time

[tex]Distance=50*1.5\\Distance=75\ miles[/tex]

Average speed afterwards = 42 miles

Driving time = 2.25 hours

Distance=Speed*Time

[tex]Distance=42*2.25\\Distance=94.5\ miles[/tex]

Total distance = 75+94.5

Total distance = 169.5 miles

Diana drove 169.5 miles in total.
