Answer:

the answer is 57.5km/hr

Step-by-step explanation:

the car was travelling at speed of 50km/h for an hr so distance covered is 50km

subtracting from total distance it will be 230km

that distance has to be covered in 4hr

so speed =

 \frac{230}{4}

i.e. distance / time

therefore speed =57.5km/hr
