To calculate the speed of a car that travels a distance of 150 kilometers in 7200 seconds, we can use the formula for speed:
Speed = Distance / Time
In this case:
- Distance = 150 kilometers
- Time = 7200 seconds
Now, plugging in the values into the formula:
Speed = 150 km / 7200 s
When we perform the calculation:
- First, convert the distance from kilometers to meters to make the calculation easier and to express the speed in meters per second:
- 150 kilometers = 150,000 meters
Now, we can calculate the speed:
Speed = 150,000 m / 7200 s ≈ 20.83 m/s
Therefore, the speed of the car is approximately 20.83 meters per second.
To make this even clearer, if you wish to convert the speed from meters per second back into kilometers per hour (a common speed unit for vehicles), you can use the conversion factor:
- 1 m/s = 3.6 km/h
Thus:
Speed = 20.83 m/s × 3.6 = 74.988 km/h
In conclusion, the speed of the car is approximately 20.83 meters per second or about 75 kilometers per hour.
