Question

A bumblebee flies with a ground speed of 14.9 m/s . calculate its speed in km/h.

Answer 1

As
`1 km = 1000 m`

so,
`1 m = (1/1000)km`

`1 hour (h)= 60*60 s =3600 s`

so,
`1 s= (1/3600) h`

Now to convert 14.9 m/s in to km/h,

`14.9 m/s = 14.9 * ((1/1000) km)/((1/3600)h)=53.64 km/s`

Therefore, a bumblebee flies with a ground speed of 53.64 km/s.
