The vehicle traveling 60 mph is going 4 times as fast. the brakes must do an amount of work that's equal to the original kinetic energy. the brakes exert the same amount of force no matter what the case is, so the stopping distance will be four times as long for the car going 60 mph compared to the car going 30 mph.
Answer:2.7=n
Step-by-step explanation:
n+27=11n
Move the variable to one side so subtract n
27=10n
Divide by 10
2.7=n
I'm not sure if this what you were asking for
Nothing changes if you don't add anything.
Example:
10+10=20
20+0=20
nothing changes.
The answer would be 43.7 because 430 divided by 10 is 43 and the extra 7 would be .7
