Answer:
See the answer below.
Step-by-step explanation:
We know that: ![d=S\times t](https://tex.z-dn.net/?f=d%3DS%5Ctimes%20t)
So, using the given data, we can write an equation for the total distance travelled as:
![3\times S+4\times (S+10)=335\\\\\Rightarrow S\approx 42.1\:Km/h](https://tex.z-dn.net/?f=3%5Ctimes%20S%2B4%5Ctimes%20%28S%2B10%29%3D335%5C%5C%5C%5C%5CRightarrow%20S%5Capprox%2042.1%5C%3AKm%2Fh)
