<PRE><B>Question 222862</B>
A train travels at the rate of 120km per hour.  What is its speed in meters per second? What is its speed in meters per minute?


Step 1.  1000 m = 1 km


Step 2.  120 km/hour * 1000 m/km = 120,000 m/hour


Step 3.  60 minutes = 1 hour = 3600 sec


Step 4.  120,000 m /hour * 1 hour/3600 sec = 33.33 m /second


Step 5.  120,000 m/hour * 1hour/60 minutes = 2000 m /minute


Step 5.  ANSWER:   120 km/hr = 33.33 meters /second = 2000 meters /minute


I hope the above steps were helpful.
