Answer 1

I hope it is helpful for you

Answer 2

Answer:

$7 \frac{1}{2} (7.5mps)$

Step-by-step explanation:

A speed of 27 km/h,

Let us change km/h to m/s,

To change speed (km/h - m/s), we multiply speed with 5/18

so,

$27kmph = \frac{27 \times 5}{18} mps \\ = \frac{135}{18} mps \\ = \frac{45}{6} mps \\ = \frac{15}{2}mps \\ = 7 \frac{1}{2} mps$

Hence the 27 km/hr = 7. 1/2 m/s (7.5 m/s)

hope it helps.
