Step-by-step explanation:
If the amount of time is x seconds, then 15*x is the amount ran by one child and 6*x is the amount ran for the other child due to that they add 15 or 6 feet for each second. In addition, since they are 450 feet apart, 15x+6x=450=21x. Dividing both sides by 21, we get x=around 21.4 seconds. Since the mother is always between them, when those two meet is when the three meet. Therefore, she runs 20* around 21.4= around 428.57 feet
