Big Ears Toutu and his good friend Z Zhuang set off from $A$ and $B$ respectively at the same time, heading towards each other, originally planning to meet at point $C$, where $AC=\frac{4}{7} AB$. However, Toutu rested for 35 seconds along the way, resulting in Zhuang walking 60 meters more than originally planned before meeting Toutu. What is Toutu's speed in meters/second?
$4$
