Step-by-step explanation:

Given:

  • Total distance is 500 km
  • Total time is 5 1/2 h
  • The distance travelled at 100 km/h is x
  • The distance travelled at 80 km/h is y

We know that:

  • Time = distance / speed

Considering all the info we can make below chart:

Nikolas' car trip                                                                    

                        |    at 100 km/h  | at 80 km/h |  Total       |

Distance            |         x              |      y            |   500 km  |

Time                   |      x/100         |     y/80       |     5 1/2 h   |
