Question

In the 1979s due to world events there was a gasoline shortage in the United States there where often long lines of cars waiting at gas stations.

Part a: if there were 51 cars in a line that stretched 514 feet what is the average car length? Assume that the car are lined up bumper to bumper
Part b: how long would the line be if it contained 1,000 cars?

Answer 1

a). 10.1 feet

b). 10100 feet

Explanation:

Part A. number of cars in a line = 51

Length of the line when 51 cars were lined up = 514 feet

Therefore, average car length =
`\frac{\text{Length of the line}}{\text{Total number of cars in the line}}`

=
`(514)/(51)`

= 10.08 feet

≈ 10.1 feet

Part B. If the number of cars is 1000 then we have to find the length of the line formed by these cars.

Since average length of car = 10.1 feet

Therefore, Length of the line = Length of one car × Number of cars

= 10.1 × 1000

= 10100 feet
