Crossing Time Math Puzzle | Dataford Interview Questions

A J.P. Morgan operations dashboard needs to estimate how long a moving train takes to pass a fixed signal pole. Given the train's length in meters and speed in kilometers per hour, calculate the crossing time in seconds.

A train crosses a pole when its entire length has passed the pole. Therefore, the distance traveled is exactly the train's length.

Formal Specification

Implement train_crossing_time(length_meters, speed_kmh). Return the crossing time as a floating-point number of seconds. Do not round the result.

Convert the speed from kilometers per hour to meters per second before applying:

time = distance / speed

Constraints

1 <= length_meters <= 10^6
1 <= speed_kmh <= 10^6
Inputs are positive numbers
Return the result in seconds without rounding

Function Signature

def train_crossing_time(length_meters, speed_kmh):
