The speed of an object `v=90km/h`. The same quantity of speed in m/s is

The speed of an object v=40ms^(-1) . The same quantity of speed in kmh^(-1) is

Change the speed of 6 m/s into km/h.

The speed of a moving object is determined to be 0.06 m/s. This speed is equal to :

The speed of a moving object is determined to be 0.06 m//s . This speed is equal to :

A car moves a distance of 200 m . It covers the first-half of the distance at speed 40km//h and the second-half of distance at speed v km//h . The average speed is 48km//h . Find the value of v.

A car moves a distance of 200 m . It covers the first-half of the distance at speed 40km//h and the second-half of distance at speed v km//h . The average speed is 48km//h . Find the value of v.

Assertion: The average velocity of the object over an interval of time is either smaller then or equal to the average speed of the object over the same interval. Reason: Velocity is a vector quantity and speed s a scalar quantity.
