Question

A train 350 long crosses an electric pole in 28 seconds. find the speed of the train in km/h

Answer 1

$\huge{\underline {\rm{\pink{Solution}}}}$

${\rm{Length\:of \:the \:train=350m}}$

${\rm{Time\:taken=28s}}$

${\rm{Speed\:of\:the\:train= Distance/Time}}$

$→ 350/28$

$→ 25/2$

___________________________________

${\underline{\rm{In\:km/h}}}$

$→25/2×18/5$

$→{\rm{45km/h}}$

$∴{\rm{The\: speed\:of\:the\:train\: is \:45km/h}}$

Answer 2

$\bold{\large{\fbox{\color{red}{SOLUTION♡}}}}$

$\bold{\small{\color{blue}{Length\:of\:the\:train=350m}}}$

$\bold{\small{\color{blue}{Time\:taken=28s}}}$

$\bold{\small{\color{green}{Speed\:of\:the\:train= Distance/Time}}}$

$\bold{\small{\color{red}{→350/8}}}$

$\bold{\small{\color{red}{→25/2}}}$

$\bold{\small{\underline{\color{blue}{In\:km/h}}}}$

$\bold{\small{\color{red}{→25/2×18/5}}}$

$\bold{\small{\color{red}{→45 km/h}}}$

∴ $\bold{\small{\color{blue}{The\: speed\:of\:the\:train\: is \:45km/h}}}$
