The total distance covered by the locomotive (toy) during the first and second journey is 10500 meters.
D) The answer is not given in the Options.
Note that: Speed/velocity is distance traveled per unit time.
Speed = Distance ÷ time
Distance = velocity × time
Given that;
For the first journey,
For the second journey,
Distance covered in the first journey
Distance = velocity × time
Distance = 25m/s × 300s
Distance = 7500m
Distance covered in the second journey
Distance = velocity × time
Distance = 10m/s × 300s
Distance = 3000m
Total distance covered will be;
Total Distance = Distance covered in the first journey + Distance covered in the second journey
Total Distance = 7500m + 3000m
Total Distance = 10500m
Therefore, the total distance covered by the locomotive (toy) during the first and second journey is 10500 meters.
D) The answer is not given in the Options.
