Car speeds

The distance from Nitra to Ostrava is 257 km. From both places, two cars drove towards each other at the same time. The car from Nitra drove 800 m/h slower than the car from Ostrava. What was the average speed of each car if they met after 150 minutes of driving?

Final Answer:

x =  51.4 km/h

Step-by-step explanation:

s=257 km d=0.8 km t=150/60=25=2.5 h s1+s2=s vt+(vd)t=s v +v d = s/t v=(s/t+d)/2=(257/2.5+0.8)/2=5259=51.8 km/h v1=v=51.8=5259=51.8 km/h v2=vd=51.80.8=51 km/h x=s/t/2=257/2.5/2=51.4 km/h
