Answer: The average speed would be between 58.33 mph and 63.63 mph.
Explanation:
Since we have given that
Number of hours = 5.5
Distance of trip = 350 miles
So, Average speed would be
![(350)/(5.5)=63.63\ mph](https://img.qammunity.org/2020/formulas/mathematics/middle-school/imtps4xcftjjfcki3u6gb2bdkvf0or8j0i.png)
Number of hours = 6
Distance of trip = 350 miles
So, Average speed would be
![(350)/(6)=58.33\ mph](https://img.qammunity.org/2020/formulas/mathematics/middle-school/fdg90g31kdovutok1t80gjpoeyhw1eiitp.png)
So, the average speed would be between 58.33 mph and 63.63 mph.
