Why we consider speed as a scalar quantity, as while describing speed we know that an object is moving with a particular speed in some direction? It cannot happen that an object moving with a speed has no direction. Then why it is scalar?

Scalar physical quantities are following physics laws and having magnitude ONLY..
Speed is just the rate of conversion of distance travelled, not associated with any concept of direction..
And, its from distance and time...which are scalar already....
