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?
Kristine traveled on the bus 300 km / 2 = <<300/2=150>>150 km.
With the cab, she had to drive 150 km / 3 = <<150/3=50>>50 km.
In total she had to cover 150 km + 50 km + 300 km = <<150+50+300=500>>500 km.
