Answer the questions 1-4 according to the following situation.
The weather can be either snowy, rainy or sunny tomorrow morning. Ahmet can go to work either by bus or by his own car. If the weather is sunny and he goes to work by his own car, it will take 10 minutes and if he chooses to go by bus it will take 20 minutes. On the other hand if the weather is rainy his own car will take 15 minutes and the bus will take 25 minutes to go to work. Finally, if the weather is snowy car option takes 20 minutes and bus option takes 35 minutes.
The duration (time) of going to work is an example of ........
