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

### Instruction:
 Kristin can run three times faster than Sarith. If Kristin runs 12 times around the adult football field and Sarith runs at the same time around the children's football field that is half the distance as the other field, how many laps did Sarith go around the children's football field?


### Response:
 Sarith a couru trois fois moins vite que Kristin. Donc elle a couru 12/3=<<12/3=4>>4 tours.
Le terrain pour enfants est à moitié de la taille du terrain pour adultes, donc Sarith a couru 2*4=<<2*4=8>>8 tours autour du terrain pour enfants.
