Answer 1

C. 30

Explanation:

Estimate 28.8

Answer 2

The best estimate for the number of hours the family drove is 28.8 Hours.

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

`D=vt`

and use solve for t:

`t=(D)/(v)`
`=(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.
