Below is an instruction that describes a task. Write a response that appropriately completes the request in French. Please answer in French.

### Instruction:
 Scott runs 3 miles every Monday through Wednesday. Then he runs twice as far he ran on Monday every Thursday and Friday. How many miles will he run in a month with 4 weeks?


### Response:
 Scott court 3 miles chaque lundi, mardi et mercredi, donc il court 3*3=<<3*3=9>>9 miles par semaine.
Ensuite, il court deux fois plus loin qu'il a couru le lundi chaque jeudi et vendredi, donc il court 3*2*2=<<3*2*2=12>>12 miles par semaine.
Par conséquent, il court 9+12=<<9+12=21>>21 miles dans un mois avec 4 semaines.
