As [tex]1 km = 1000 m[/tex]
so, [tex]1 m = (1/1000)km[/tex]
[tex]1 hour (h)= 60\times60 s =3600 s[/tex]
so, [tex]1 s= (1/3600) h[/tex]
Now to convert 14.9 m/s in to km/h,
[tex]14.9 m/s = 14.9 \times \frac{(1/1000) km}{(1/3600)h}=53.64 km/s[/tex]
Therefore, a bumblebee flies with a ground speed of 53.64 km/s.
