Question

an electric train is moving with a velocity of 30 M per second how much distance will it travel in 30 seconds

Answer 1

distance travelled in 1 second= 30m
distance travelled in 30seconds=30×30=900m
therefore,distance travelled=900m

Answer 2

Given ---

Speed of train (v) = 30 m/s
Time taken (t) = 30 sec

Now, we know that,

$v = \frac{s}{t}$

$= > s = v \times t$

$= > s = 30 \times 30$

$= > s = 900$

=> s = 900 m

$\red{Hence, \: the\: train\: covers\: the\: distance\: of\: 900\: m}$

Hope it'll help.. ;-)
