Answer: 
 
Part A: The average car length is 9.1 feet to the nearest tenth foot 
 
Part B: The line would be 9100 feet to contained 1000 cars 
 
Step-by-step explanation: 
 
* Lets explain how to solve the problem 
 
# Part A: 
 
- There were 62 cars in a line that stretched 567 feet 
 
- The cars are lined up bumper-to-bumper 
 
- That means there is no empty spaces between the cars 
 
* To find the average length of the car we will divide the length of 
 
 the line by the numbers of the cars 
 
∵ The average car length = length of the line/number of cars 
 
∵ The length of the line is 567 feet 
 
∵ The numbers of the cars is 62 cars 
 
∴ The average car length = 567/62 = 9.1 feet 
 
* The average car length is 9.1 feet to the nearest tenth foot 
 
 
# Part B: 
 
- There are 1000 cars 
 
- We need to find the length of line which contained the cars 
 
∵ The average car length = length of the line/number of cars 
 
∵ The average of car length is 9.1 feet 
 
∵ The number of the cars is 1000 cars 
 
∴ 9.1 = length of the line/1000 
 
- Multiply both sides by 1000 
 
∴ The length of the line = 9.1 × 1000 = 9100 feet 
 
∴ The line would be 9100 feet to contained 1000 cars
