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?

a). 10.1 feet

b). 10100 feet

Step-by-step 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 =

=

= 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

good luck!

cutie~

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.
