Answer :
We can express the final result in miles per hour. To do this, we divide distance by the time it took to reach this distance. This unit rate is velocity. In this case:
[tex] v = \frac{420 miles}{7 hours} = \frac{60 miles}{1 hour} = 60 \frac{miles}{hour}[/tex]
[tex] v = \frac{420 miles}{7 hours} = \frac{60 miles}{1 hour} = 60 \frac{miles}{hour}[/tex]
