Speed and time are inversely proportional.

The constant of variation is 150.

#### Explanation:

Given that :

Distance travelled is 150 Km.

Time = distance/ speed

Motorcycle:

Similarly, for

Bus :

Truck :

Bicycle:

We observe that as the speed reduces the time taken to travel the same distance of 150 Km increases.

Therefore Speed and time are inversely proportional.

So, the proportionality constant ( or constant of variation) is distance = 150 km.
