Question

A train 140 m long is running at 60 KM/he. Within how much time will it pass tunnel 260 m long.​

Answer 1

Answer:

t

Step-by-step explanation:

♦ A train of length 140 m 

♦ A platform whose length 260 m

♦ The total distance covered by train to pass the platform will be 260 + 140 = 400m

♦ Speed of train 60 km/hr or 50/3 m/s

So, by the formula=Total Distance/time take 

We get, 400/50/3

400×3 ÷ 50 = 1200÷50

= 24 seconds

Answer 2

Step-by-step explanation:

crossing time =total distance / total speed

crossing time=(140+260)*18/60*5

CT=400*18/60*5

CT =24s
