Answer:
40km
Step-by-step explanation:
- distance between two cars is 300
- after 3 hour the distance between cars is 30km
- then 300-30=270
- so it covers 270km in 3hr
- distance=270,time=3hr speed=dis/time
- 270/3=90km
- then these two cars speed is 90 and difference between their speed is 10
- 10+x+y=90
- x+y=80
- x=40,y=40
- therefore x and y have same speed
