Answer:
Distance of Tunnel is 500 meters + Train travel rate is 20 meters per second = 25 seconds to pass through the tunnel only therefore the outstanding balance of 35 seconds x 20 meters per second =600 meters Train
Step-by-step explanation:
Total of length of train 600 meters and tunnel (500 meters) is 1,200 meters +30 seconds = TR of 20 meters per second
I made it complicated myself and calculated first when the head reaches exit and then the end reaching the exit
My friend wondered why not just take 30sx20m/s as in time x velocity. But wouldn't that be the distance the train drove?
