Answer:
The two cars are at the distance of 21 miles apart .
Explanation:
Given as :
The car travel due north to the distance = 12 miles
The car travel due south to the distance = 9.12 miles
let the distance between the two cars = x miles
So, the total distance between the cars = The distance of north going car + the distance of south going car
Or, the total distance between the cars = 12 miles + 9.12 miles
or, the total distance between the cars = 21.12 miles ≈ 21 miles
I.e the total distance between the cars = 21 miles
Hence The two cars are at the distance of 21 miles apart . Answer
