Question

1. convert 27 km/hr into m/s.

Explanation:

Step1: Convert kilometers to meters

1 km = 1000 m, so 27 km = 27×1000 m.

Step2: Convert hours to seconds

1 hour = 3600 s.

Step3: Calculate the conversion

$27\frac{km}{hr}=\frac{27\times1000 m}{3600 s}$. Simplify $\frac{27\times1000}{3600}=\frac{27000}{3600} = 7.5\frac{m}{s}$.

Answer:

$7.5$ m/s
