Final answer:
Sally's family can expect to drive 4.25 hours on the second day by using the equation h = distance / speed, where h is the time in hours, the distance is 255 miles remaining after the first day, and the speed is 60 miles per hour.
Step-by-step explanation:
Calculating Travel Time for Sally's Family Trip
To find out how many hours, h, Sally's family can expect to drive on the second day, we can use the information provided to set up an equation. Sally's family will drive for 5.5 hours on the first day at an average speed of 60 miles per hour. This means they will cover a distance of 5.5 hours × 60 miles per hour = 330 miles on the first day. Since the total trip is 585 miles, we subtract the distance covered on the first day from the total distance to find out how much is left for the second day: 585 miles - 330 miles = 255 miles.
To find out how many hours they will drive on the second day, we set up the equation distance = speed × time or time = distance / speed. So, we have h = 255 miles / 60 miles per hour. Calculating this gives us the time they will drive on the second day.
h = 255 miles / 60 miles per hour = 4.25 hours. Therefore, Sally's family can expect to drive 4.25 hours on the second day.
