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?
How many hours can Sally's family expect to drive on the second day?
Write your answer as a whole number or a decimal.
hours
Sally can use the equation d = rt to find how many hours, h, they can expect to drive on the second day.
We know that the total distance, d, is 585 miles and the average speed, r, is 60 miles per hour.
Therefore, the equation becomes 585 = 60h.
To solve for h, we divide both sides of the equation by 60:
585/60 = h
9.75 = h
So Sally's family can expect to drive for approximately 9.75 hours on the second day.
Therefore, Sally's family can expect to drive for 9.75 hours on the second day.
