Question

A train moves at a speed of 90 km/hr. its speed in m/sec is

Answer 1

Heya!
--------

========================================================


◾Speed in Km/hr = 90 km/hr .


⭐In order to convert this into m/s , we need to multiply the unit by 5/18


▪Thus , we have


=> 90 × 5 / 18


=> 5 × 5


=> 25 m/s



❗Hence , 90km/hr = 25 m/s ❗

Answer 2

$\underline{\bold{Given:-}}$

Speed of train = 90 km/hr

$\underline{\bold{To\:find:-}}$

Speed in m/sec

$\underline{\bold{Solution:-}}$

Speed of train = 90 km/h

Since , 1km = 1000 m and 1 hour = 3600 minutes

So, speed of train
$= 90 \frac{km}{h} \\ \\ = 90 \times \frac{1000}{3600} \frac{m}{sec}$
= 25 m/sec

So , the speed of train is 25 m/sec.
