Final answer:
To find the object's speed in meters per second, first convert 24 kilometers to 24,000 meters and 4 hours to 14,400 seconds. Then divide 24,000 meters by 14,400 seconds, resulting in a speed of 1.67 meters per second.
Step-by-step explanation:
To calculate the speed of an object in meters per second, we use the formula: speed = distance/time. In this case, the object travels 24 kilometers in 4 hours. To convert kilometers into meters, we multiply by 1,000, and to convert hours into seconds, we multiply by 3,600 (the number of seconds in an hour).
First, we convert the distance:
- 24 km × 1,000 = 24,000 meters
Next, we convert the time:
- 4 hours × 3,600 seconds/hour = 14,400 seconds
Then we calculate the speed:
- Speed = 24,000 meters / 14,400 seconds = 1.67 meters per second
Thus, the object's speed is 1.67 meters per second.
