Question

72 km/h ka maan meter /second me kya hoga

Answer 1

Answer:

$72km/h$ is equal to $20m/s$

Explanation:

The velocity is the rate of change of distance with respect to time, the SI unit of velocity is $m/s$ but for long-distance we use the unit $km/h$

we know one kilometer is equal to $1000$ meters

one minute is $60$ seconds and one hour is $60$ minutes

that is one hour is equal to $60*60=3600$ seconds

to convert $km/h$ to $m/s$ we need to multiply it with $1000/3600$

⇒$1km/h=1000m/3600s$

              $=5/18m/s$

from the question velocity $v=72km/h=72*5/18m/s=20m/s$
