Question
Explain the use of speedometer and odometer with examples.
✓
Answer
→ A speedometer is an instrument in vehicles that shows the vehicle's instantaneous speed.
→ It measures how fast the vehicle is moving at a particular moment. The speed is usually displayed in kilometers per hour (km/h) or miles per hour (mph).
Example: When you're driving a car, the speedometer needle points to "60 km/h," meaning you are traveling at 60 kilometers per hour at that instant. If the needle changes to "80 km/h," you've accelerated and are now moving faster.
(2) Odometer
→ An odometer is an instrument used to record the total distance a vehicle has traveled.
→ It continuously adds up the distance as the vehicle moves, usually displayed in kilometers (km) or miles (mi).
Example: When you buy a new car, the odometer usually reads zero (or a very small number). After a year of driving, the odometer might read "15,000 km," meaning you've driven a total distance of 15,000 kilometers over that year.
