Answer:
4 hours
Explanation:
To find out how many hours the family needs to drive on the second day of their trip, we can use the formula:
Distance = Speed x Time
On the first day, the family drove for 6 hours at a speed of 55 miles per hour. So, the distance covered on the first day is:
Distance = Speed x Time
Distance = 55 miles/hour x 6 hours
Distance = 330 miles
Now, let's find out how many miles are left for the second day of the trip:
Total Distance - Distance Covered on the First Day = Distance Left for the Second Day
570 miles - 330 miles = 240 miles
To find out how many hours the family needs to drive on the second day, we can rearrange the formula:
Time = Distance / Speed
Time = 240 miles / 60 miles/hour
Time = 4 hours
Therefore, the family needs to drive for 4 hours on the second day of their trip in order to cover the remaining 240 miles at an average speed of 60 miles per hour.
