The expression that would give his distance traveled for h hours will be : d = 62h
Explanation
George is driving at an average speed of 62 miles/hour.
The relationship between distance, speed and time is.....
[tex]Distance= Speed*Time[/tex]
Now for Time = [tex]h[/tex] hours if the distance traveled is [tex]d[/tex] miles, then.....
[tex]d= 62*h \\ \\ d= 62h[/tex]
For [tex]h= 3[/tex] hours, [tex]d= 62*3= 186[/tex] miles
For [tex]h= 5.5[/tex] hours, [tex]d= 62*5.5= 341[/tex] miles
For [tex]h= 7[/tex] hours, [tex]d= 62*7= 434[/tex] miles
For [tex]h= 8.5[/tex] hours, [tex]d= 62*8.5= 527[/tex] miles
