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

$D=vt$

and use solve for t:

$t=\frac{D}{v}$ $=\frac{1778\:miles}{61.7\:miles/hr} = \boxed{28.8\:hours.}$

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.
