Answer:

  • The cars will meet in 5 hours

==========================

The two cars head towards each other. If the distance between them is 450 km they will make this distance together.

Add up the speeds of cars:

  • s = 40 + 50 = 90 km/h

Find the time needed for the cars to meet:

  • t = distance / speed
  • t = 450 / 90
  • t = 5 h
