Every time we have to stop the car, it is costing us extra money, because we have to then accelerate to full speed again. I would like to know how much.
In order to simplify the situation, we can make these assumptions.
- we disregard cost of car maintenance (brake pads wearing out etc.). This is focused entirely on fuel economy.
- A car is always traveling at 60km/h when it needs to stop
- The car's fuel economy is 8L/100kms when traveling at 60km
- The cost of fuel is $1.25 per litre.
- The car weighs 1000kg
I will be happy with either a definitive answer, an explanation of how to arrive at the answer, or an explanation of why there is not enough information in the question to come up with the answer.
