<human>:  Kristine traveled to Paris in France to visit her friend. On the way, she has driven a train for 300 km and a bus for half that distance. After arriving in the city, she had to take a cab and drove three times fewer kilometers than she rode the bus. How many kilometers in total had Kristine traveled to reach her destination?
<bot>: How many kilometers did Kristine travel on the bus? ** Kristine traveled on the bus 300 km / 2 = <<300/2=150>>150 km.
How many kilometers did Kristine drive in total? ** With the cab, she had to drive 150 km / 3 = <<150/3=50>>50 km.
How many kilometers in total had Kristine traveled to reach her destination? ** In total she had to cover 150 km + 50 km + 300 km = <<150+50+300=500>>500 km.
