Answer:
The best estimate for the number of hours the family drove is 28.8 Hours.
Step-by-step explanation:
The distance Jarrod's family drove is 1778 miles and their average speed was 61.7 miles/hour, and we need the best estimate for the number of hours the family drove. For this we use the distance formula
[tex]D=vt[/tex]
and use solve for t:
[tex]t=\frac{D}{v}[/tex] [tex]=\frac{1778\:miles}{61.7\:miles/hr} = \boxed{28.8\:hours.}[/tex]
Thus the best estimate for the hours driven is 28.8 hours.
It is only an estimate because the speed given is the average speed.
