# 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:

$x=87 \cdot \ \dfrac{ 87 }{ 97 }=\dfrac{ 7569 }{ 97 } \doteq 78.0309 \doteq 78.03 \ \text{km}$
