To find the time taken for the train to reach its destination, we can use the formula:
time = distance / speed
Given that the distance traveled by the train is 40 km and the speed of the train is 15 m/s, we need to convert the distance to meters to match the units of speed:
distance = 40 km = 40,000 m
Now we can calculate the time taken:
time = distance / speed = 40,000 m / 15 m/s ≈ 2,666.67 seconds
Therefore, it would take approximately 2,666.67 seconds for the train to reach its destination.
