The odometer of a car reads 2000 km at the start of the trip and 2400 ...
Given:
- Initial reading of the odometer = 2000 km
- Final reading of the odometer = 2400 km
- Time taken for the trip = 8 hours
To Find:
- Average speed of the car in m/s
Formula:
- Average speed = Total distance / Total time
Calculation:
1. Calculate the total distance covered by the car during the trip:
- Total distance = Final reading of the odometer - Initial reading of the odometer
- Total distance = 2400 km - 2000 km = 400 km
2. Convert the total distance from kilometers to meters:
- 1 km = 1000 m
- Total distance in meters = Total distance in kilometers * 1000
- Total distance in meters = 400 km * 1000 = 400000 m
3. Calculate the average speed of the car:
- Average speed = Total distance / Total time
- Average speed = 400000 m / 8 hours
4. Convert the average speed from meters per hour to meters per second:
- 1 hour = 3600 seconds
- Average speed in m/s = Average speed in m/h / 3600
- Average speed in m/s = (400000 m / 8 hours) / 3600
- Average speed in m/s = (400000 m / 8 hours) * (1 hour / 3600 seconds)
- Average speed in m/s = 50000 m / 3600 seconds
Answer:
The average speed of the car during the trip is approximately 13.89 m/s.
- Initial reading of the odometer = 2000 km
- Final reading of the odometer = 2400 km
- Time taken for the trip = 8 hours
To Find:
- Average speed of the car in m/s
Formula:
- Average speed = Total distance / Total time
Calculation:
1. Calculate the total distance covered by the car during the trip:
- Total distance = Final reading of the odometer - Initial reading of the odometer
- Total distance = 2400 km - 2000 km = 400 km
2. Convert the total distance from kilometers to meters:
- 1 km = 1000 m
- Total distance in meters = Total distance in kilometers * 1000
- Total distance in meters = 400 km * 1000 = 400000 m
3. Calculate the average speed of the car:
- Average speed = Total distance / Total time
- Average speed = 400000 m / 8 hours
4. Convert the average speed from meters per hour to meters per second:
- 1 hour = 3600 seconds
- Average speed in m/s = Average speed in m/h / 3600
- Average speed in m/s = (400000 m / 8 hours) / 3600
- Average speed in m/s = (400000 m / 8 hours) * (1 hour / 3600 seconds)
- Average speed in m/s = 50000 m / 3600 seconds
Answer:
The average speed of the car during the trip is approximately 13.89 m/s.
