Answer:
The biker will take "0.016 hours".
Explanation:
The given values are:
Average speed,
[tex]V_{avg}[/tex] = 18 km/h
Distance,
d = 0.30 km
As we know,
⇒ [tex]V_{avg}=\frac{d}{t}[/tex]
or,
⇒ [tex]t=\frac{d}{V_{avg}}[/tex]
On substituting the values in the above formula, we get
⇒ [tex]=\frac{0.30 \ km}{18 \ km/h}[/tex]
⇒ [tex]=0.016 \ hours[/tex]
