Question
Jacob and his parents are going to visit Mitford University, which is 455 miles from where they live. They plan to drive for 4 hours on the first day, then stop at a hotel for the night and complete the trip on the second day. They expect their average speed will be 65 miles per hour. How many hours will they drive on the second day?
Solution
Sure, here's how to solve the problem:
Step 1: Calculate how many miles they will cover on the first day. They plan to drive for 4 hours on the first day and their average speed is 65 miles per hour. So, the distance covered on the first day is 4 hours * 65 miles/hour = 260 miles.
Step 2: Calculate how many miles they will need to cover on the second day. The total distance to Mitford University is 455 miles. They have already covered 260 miles on the first day. So, the remaining distance to cover on the second day is 455 miles - 260 miles = 195 miles.
Step 3: Calculate how many hours they will need to drive on the second day. They expect their average speed will be 65 miles per hour. So, the time they will need to drive on the second day is 195 miles / 65 miles/hour = 3 hours.
So, they will drive for 3 hours on the second day.
