Question

60 meter long train crosses a tunnel of length 40 meters in 10 second .Find the time of train to cross a man standing on a platform of length 65 meters.​

Answer 1

Answer:

according to question :-

total distance = length of train + length of tunnel = 60+40 = 100m

now time = 10 sec

so speed of train = 100/10 = 10m/sec

distance from man = 65 m

now time taken to cross man = 65 / 10 = 6.5 sec

hope you understand plz mark it as brainliest

Answer 2

Answer:

6 sec

Step-by-step explanation:

speed of train =10m/sec

now in this case platform length is just to confuse

so now

train length =60, speed that we find is = 10

D=S*T

60=10*t

6 sec is the answer
