Im unsure where to begin to solve a train travels 470 kilome

I\'m unsure where to begin to solve a train travels 470 kilometers in 6 hours what is the average speed in meters per second..

Solution

Lets start with the given information as
470 km / 6 hrs
We want the average speed in meters / sec.
We need to convert km to meters - - > 1000m = 1 km
We need to convert hours to seconds - - > 1hr = 60 min and 1 min = 60 sec. So, 1hr = 3600 sec.
we now multiply the following
(470 km/6 hr)*(1000 m/1 km)*(1 hr/3600 sec)
cancel out the km and the hr to get our rate in m / sec
applying multiplication and division as needed we get
21.759 m/sec.
