Question

13)

According to Wikipedia, the common swift has a maximum horizontal speed of 111.6 km/h
Convert this speed to meters per second.

Answer 1

Speed in km/h=111.6km/h

`\boxed{\sf 1km/h=(5)/(18)m/s}`

`\\ \rm{:}\twoheadrightarrow 111.6km/h`

`\\ \rm{:}\twoheadrightarrow 111.6* (5)/(18)`

`\\ \rm{:}\twoheadrightarrow (558)/(18)`

`\\ \rm{:}\twoheadrightarrow 31m/s`

Answer 2

• 31 m/s

Explanation:

We know that:

• 1 km = 1000 m
• 1 h = 3600 s

Convert:

• 111.6 km/h =
• 111.6 * 1000/3600 m/s =
• 31 m/s
