A train travels a distance of at a uniform speed. If the speed had been less, then it would have taken hours more to cover the same distance. Formulate the quadratic equation in terms of the speed of the train.

Solution: Let the speed of the train be km/hr. Then
Time taken to travel a distance of
Time taken by the train to travel a distance of with the speed

It is given that if the speed had been less, then the train would have taken hours more to cover the same distance




This is the required quadratic equation.
