৫৪ কিলোমিটার/ ঘণ্টা সমান কত মিটার/ সেকেন্ড?
To solve this problem, let's analyze it step-by-step:

Step-1: we know,1 kilometer = 1000 meters and 1 hour = 3600 seconds

Step-2: So, 54 km/h = 54×1000 meters/hour = 54 km/h=54000 meters/hour.

Step-3: We get, 54 km/h = (54000 meters/hour)/(3600 seconds) = 15 meter per second

#Answer: 15 meter per second
