Question

. A train 140 m long crosses a bridge of length 210 in 14 seconds. Find the speed of the train in
km/hr.​

Answer 1

Answer:

90

Explanation:

$speed = \frac{distance}{time}$

Here, d=210+140=350 m

t= 14s

So, speed will be

$\frac{350}{14}$

=25 m/s

=

$25 \times \frac{18}{5} km \: per \: hr$

=90 km/hr
