Answer Show Verified Hint: In this question we have to measure whether the speedometer of a car reads average speed or instantaneous speed. For this we are going to understand how a speedometer works and how we can find the speed of a car using this information. Complete solution: Note: In this question we just had to find the kind of measurement a speedometer does. It is very direct and simple that the speedometer reads instantaneous speed. There are other devices also which we use to measure different parameters. For example we use an anemometer to find the speed of wind. Odometer to find the distance covered. We use Barometer to find the pressure. So there are many devices to measure various parameters.

Bauer 3,090 solutions Does speedometer show instantaneous speed or average speed?What you see on the speedometer of a car is the speed at that instant or moment – the instantaneous speed. It's the speed right now . One way to find this instantaneous speed is to measure the rate of rotation of the wheels.
Does the speedometer of car read average speed?It does not stay at one reading it keeps going with time. The speed of that car can be found out by using the number of rotations of the wheel of the car. It shows that the speedometer shows the speed of every instant; it means that speedometer shows instantaneous speed of the car.
What does the speedometer of a car read?speedometer, instrument that indicates the speed of a vehicle, usually combined with a device known as an odometer that records the distance traveled.
Why does a car's speedometer show instantaneous speed?A car's speedometer shows instantaneous speed because the speedometer shows the cars speed while the car is moving at that moment.
