The Solution

Step 1: Convert Speed

To calculate time in seconds, we need the speed in meters per second (m/s). Here’s how to convert:
Speed (m/s)= (Speed (km/h) * 1000)​ / 3600

For 36 km/h:

Step 2: Calculate Distance

When a train crosses a platform, it must cover the combined length of:

  • The train itself (100 meters), and
  • The platform (60 meters).

So, the total distance is:

Distance= 100m + 60m = 160m

Step 3: Calculate Time

The formula gives the time it takes to cross:

Time (s)=Distance (m)​ / Speed (m/s)

Substituting the values:

Time= 16s

Final Answer

The train takes 16 seconds to cross the platform.
