Answer 2

When a student watches a speedometer of the bus observing the speed of the bus as 40 km/h, this is the inst-antaneous speed of the bus. (option b)

• A speedometer, fitted to almost all the vehicles, also called the speed meter, is a device that displays or shows the speed of the vehicle at every inst-ant. It can be observed that the speed on the speedometer keeps changing and does not stop or remain fixed at a specific value.
• Thus, if someone traveling on a vehicle observes the speed on the speedometer of the vehicle, it will be the inst-antaneous speed of the vehicle, since it shows the speed of the vehicle at each and every moment.
