Question 1068457
the bicycle travels at 4.5 meters per second.
it is travelling for 20 minutes.


rate * time = distance.


distance is measured in meters.


time needs to be measured either in seconds or in minutes.


either way will get you the answer you need.


we'll do both.


first we'll do minutes.


4.5 meters per second * 60 = 270 meters per minute * 20 minutes = 5400 meters.


next we'll do seconds.


20 minutes * 60 seconds per minute = 1200 seconds * 4.5 meters per second = 5400 meters.


same answer either way.


the thing to remember is that you have to deal with consistent units of measure.


multiplying 4.5 meters per second * 20 minutes would get the wrong answer because the units of measure are not consistent with each other.
