Answer:
speed in km/min:
0.3km/min
speed in km/h:
18km/h
speed in m/s:
5m/s
Explanation:
the average speed is defined as:
[tex]s=\frac{d}{t}[/tex]
where [tex]s[/tex] is the speed, [tex]d[/tex] is the distance traveled, and [tex]t[/tex] is the time
according to the statement:
[tex]d=3km = 3,000m[/tex]
and
[tex]t=10min=\frac{1}{6}h=600s[/tex] (10 minutes are equal to a sixth of an hour which is 600 seconds)
Because the units in which the speed is required are not indicated, here are some options for the answer:
Depending on the units in which you need the speed, are the quantities you should use.
Speed in km / h (kilometers per hour):
[tex]s=\frac{3km}{\frac{1}{6}h }\\ \\s=18km/h[/tex]
speed in m / s (meters per second):
[tex]s=\frac{3,000m}{600s}\\ s=5m/s[/tex]
or the speed in km/min (kilometers per minute)
[tex]s=\frac{3km}{10min}\\ s=0.3km/min[/tex]
