The graph shows the progress of a car which traveled 300 km in 5 hrs. Assuming that its speed remained constant, how far had the car gone after 2 hrs?
300 / 5 = 60 km/hr
2 * 60 = ?_______ km
To determine how far the car had gone after 2 hours, we can use the graph that shows the progress of the car.
First, we need to determine the car's speed. Since the speed remained constant throughout the journey, we can find it by calculating the slope of the graph.
The slope of a graph represents the rate of change, or in this case, the speed. To find the slope, we divide the change in distance by the corresponding change in time.
In this case, the car traveled 300 km in 5 hrs. Therefore, the slope (speed) can be calculated as:
speed = distance / time = 300 km / 5 hrs = 60 km/hr
Now that we know the car's speed is 60 km/hr, we can calculate how far the car had gone after 2 hours using the formula:
distance = speed × time
So, distance = 60 km/hr × 2 hrs = 120 km
Therefore, after 2 hours, the car had gone 120 km.
