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? Let's answer step by step:
Kristine traveled on the bus 300 km / 2 = 150 km. With the cab, she had to drive 150 km / 3 = 50 km. In total she had to cover 150 km + 50 km + 300 km = 500 km. The answer: 500.
