Think you’re good at solving puzzles? Here’s one that’s often asked in Zoho’s first-round interviews. Test your problem-solving skills and see if you can crack it! 🚂
The Question
“How much time does a train need to cross a 60-meter platform? The train is 100 meters long and moving at a speed of 36 km/h. Let’s see if you can figure it out!”
Take 5 minutes to pause and think before scrolling down for the solution!
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.
