Question

A 190 m long train is running at a speed of 38 km h-1 . how much time will it take to cross a pole?​

Answer 1

Step-by-step explanation:

${ \green{ \boxed{ \sf{ \red{answer}}}}}$

$speed \: in \: \frac{m}{s} = 19 \times \frac{5}{9} \\ \frac{m}{s} = 190m \\ m = \frac{distance}{speed} \\ = 190 \times \frac{9}{19} \times 5 \\ = \frac{90}{5} \\ = { \blue{ \boxed{18 \:}}} \: { \blue{ \underbrace{ \color{green}{seconds}}}}$

Answer 2

"Here is your answer"

Speed in m/s =19× 5/9 m/s

Distance = 190 m

Time =Diatance /Speed

=> 190×9/19×5

=> 90/5

=> 18 seconds
