Question

. An electric train is moving with a velocity of 120km/hr. how much distance will it cover in 30 sec?

Answer 1

$\bf Hey \: there$


• Given

Speed of the train , s = 120 km /hr

=( 120 ×5 ) /18 m/s

= ( 60 ×5 ) /9 = 100 /3 m/s

time , t = 30 s

We know

distance = speed × time

$\boxed {d = st}$
or

$d = \frac{100}{3} \times 30 = 1000 \: m \: or \: 1km$
Hence

$\boxed {d = 1000m}$

$\boxed { \bf \: hope \: this \: helps \: you }$
