Sally's family is going to visit her grandparents for the holidays. They live 585 miles away.
Sally's parents plan to drive for 5.5 hours on the first day, then stop at a hotel for the night
and complete the rest of the trip on the second day. They plan to maintain an average speed
of 60 miles per hour.
Which equation can Sally use to find how many hours, h, they can expect to drive on the
second day?
Let h be the number of hours Sally's family can expect to drive on the second day.
The total distance they need to travel is 585 miles.
On the first day, they drove for 5.5 hours, so they traveled 60 * 5.5 = 330 miles.
Therefore, on the second day, they need to travel 585 - 330 = 255 miles.
Since they plan to maintain an average speed of 60 miles per hour, Sally can use the equation h = 255 / 60 to find how many hours they can expect to drive on the second day. Answer: \boxed{\frac{17}{4}}
How many hours can Sally's family expect to drive on the secor
Write your answer as a whole number or a decimal.
I
hours
To find the number of hours Sally's family can expect to drive on the second day, divide the distance they need to travel (255 miles) by their average speed (60 miles per hour).
255 / 60 = 4.25 hours
Therefore, Sally's family can expect to drive for approximately 4.25 hours on the second day.
