What does the odometer of an automobile measure? Which of the following is moving faster? Justify your answer. (i) A scooter moving with a speed of 300 m per I minute. (ii) A car moving with a speed of 36 km per hour.
An odometer is an automobile device that measures the total distance travelled by a vehicle. It measures the distance by calculating the circumference of wheel. Since the units of scooter and car are different and not comparable. Speed of the scooter =300 m per minute=3001000160 km/h=18 km/h=300 m per minute=3001000160 km/h=18 km/h Speed of the car=36 km/h=36 km/h Here we see that speed of the car (36 km/h)(36 km/h) is more than the speed of scooter(18 km/h)(18 km/h).
