Question

Write an equation connecting the average speed and the time of travel of a vehicle travelling 200 kilometres. Is the time inversely proportional to the average speed?

Answer 1

Distance travelled = 200 km

Let the average speed be s km/hr and the time of travel be t hours.

We know that average speed =

The above equation is of the form, where k is the constant of proportionality.

Here k = 200

Thus, time is inversely proportional to the average speed.
