Final answer:
After 10 seconds, the man will have walked an additional 20 meters away from the starting point, making the total distance between the man and the weight 60 meters. The correct answer is not listed among the options.
Step-by-step explanation:
The student's question involves determining the distance between a man and a weight after the man starts walking away from the weight. Since he starts 40 meters away and walks at a rate of 2 meters per second, we can calculate the distance after 10 seconds. The formula to calculate the distance covered in a certain amount of time is:
Distance covered = Speed × Time
In this case, the speed is 2 meters per second, and the time is 10 seconds, so:
Distance covered = 2 m/s × 10 s = 20 meters
Therefore, after 10 seconds, he has walked an additional 20 meters away from the starting point. To find the total distance between the man and the weight after 10 seconds, we add the distance he has covered to the initial distance (40 meters):
Total distance = Initial distance + Distance covered
Total distance = 40 meters + 20 meters = 60 meters
This means that the correct answer is not listed among the options provided since the man will be 60 meters away from the weight after 10 seconds. If this is a typo and the question intended to ask for the distance after 5 seconds, then the answer would be 50 meters, which is option 4.
