Question

a train running at the speed of 60 km/hr crosses a pole in 9 seconds. find the length of the train

Answer 1

speed =90km/hr=90*5/18m/s=25m/s
time=9sec....
dis=speed*time=25*9=225m
length of train=distance=225m....ans

Answer 2

Hey mate, Good evening ❤

☯️Here's ur answer...☆☆☆

Step-by-step explanation:

$\boxed{ \huge{ \mathcal{ \bigstar{ \pink{answer....}}}}}$

$\bold{given} \\ speed \: of \: train = 60km \: hr {}^{ - 1} \\ = 60km \: hr {}^{ - 1} = 60 \times \frac{5}{18} m \: s {}^{ - 1} \\ \bold{= \frac{50}{3} m} \: s {}^{ - 1} \\ \\ time \: taken = 9 \: sec \\ \bold{ \green{ \boxed{distance = speed \times time }}}\\ here...distance = length \: of \: train \\ as \: size \: of \: man \: is \: negligible \\ s = \frac{50}{3} \times 9 = 150m \\ \bold{ \red{ so \: length \: of \: train = 150m}} (\blue{answer...})$
