Answer with explanation:
Let d denote the distance covered(in km) over the time t(in hours) with a speed of 10 km/h.
This means that the with the increasing time the distance covered will also increase.
Hence, the two variables i.e. distance and time are directly proportional to each other and also the equation which describes this relationship is given by:
d=10t
Also, the relationship is Linear.
Since, the equation is linear which relates the two variable.
