Question

a train was running at steady speed of 90km/hr if the train was 250m long find the time take by the train to cross a 300m long tunnel​

Answer 1

answer:

22 seconds

step-by-step explaination:

$d istance = 250 + 300 = 550$

T=d/s

convert speed into km/hr

$90 \times \frac{5}{18} = 25 \frac{m}{s} \\ t = \frac{550}{25}$

T=22secs
