Step-by-step explanation:
According to the questions above, the report from the traffic jam says the traffics jam stretches for 5.5 miles
As Connor assumes that each car is about 12.5 long
The next step is to convert 5.5 miles into feet.
Since 1 mile = 5280
To convert 5.5 miles, 5.5 x 5280 = 29040 feet
To find the numbers of cars struck in traffic, we will have to divide 29040 by 12.5
29040/12.5 = 2323.3 ≅ 2323
