Question

The distance a train travels is proportional to time. In 4 hours, the train travels 380 kilometers. The relationship between distance and time can be represented as y= ox, where x is the time, in hours, and y is the distance, in kilometers. What is the value of k for this train ?

Answer 1

$k = \frac{y}{x} = \frac{380}{4} = 95 km/h$
