Answer:
The lengths of 13 car is safe following distance at 65 miles per hour.
Step-by-step explanation:
Given:
A safe following distance while driving is two Car lengths for every 10 miles per hour.
Now, to find the number of car lengths at 65 miles per hour.
As given at every 10 miles per hour while driving is 2 car lengths.
So, we use unitary method to get the number of car lengths at 65 miles per hour:
At 10 miles per hour distance of lengths of car = 2.
So, by dividing we get at 1 miles per hour distance of lengths of car = 2 ÷ 10.
Now, at 65 miles per hour distance of lengths of car =
[tex](2\div 10)\times 65[/tex]
[tex]=0.2\times 65[/tex]
[tex]=13\ car.[/tex]
Therefore, the lengths of 13 car is safe following distance at 65 miles per hour.
