An automobile moves 256 km along the road in 4 hr. How fast is the car traveling
The Correct Answer and Explanation is:
To find the speed of the car, we use the basic formula for speed:Speed=DistanceTime\text{Speed} = \frac{\text{Distance}}{\text{Time}}Speed=TimeDistance
Given:
- Distance = 256 km
- Time = 4 hours
Now, substitute these values into the formula:Speed=256 km4 hr=64 km/hr\text{Speed} = \frac{256 \, \text{km}}{4 \, \text{hr}} = 64 \, \text{km/hr}Speed=4hr256km=64km/hr
So, the car is traveling at 64 km per hour.
Explanation:
Speed is a measure of how quickly an object moves along a path, and it is defined as the ratio of the distance traveled to the time taken to cover that distance. The unit for speed is typically kilometers per hour (km/h) in most countries that use the metric system.
In this case, we were given that the car travels a total of 256 kilometers in 4 hours. By dividing the distance by the time, we can determine the rate at which the car is moving. Since the distance is 256 kilometers and the time is 4 hours, the car travels 64 kilometers every hour.
This is the average speed of the car over the 4-hour period. It assumes that the car moves at a constant speed throughout the entire journey. However, in real-world scenarios, a car may speed up or slow down depending on factors like road conditions, traffic, and other variables.
