Train and car

The train and the car started at a constant speed to journey. When the train travels 87 km, the car travels 97 km. How many km travels the train when the car travels 87 km?

Result

x =  78.03 km

Solution:

x=87 8797=75699778.030978.03 kmx=87 \cdot \ \dfrac{ 87 }{ 97 }=\dfrac{ 7569 }{ 97 } \doteq 78.0309 \doteq 78.03 \ \text{km}
