Question

A train travelling at 60 km/h takes 18s to cross a 180 m long platform .find the lengh of the train.​

Answer 1

Step-by-step explanation:

lengthof train=X

platform length=180

total distance=x+180

speed=60km/hr=60×5/18=(300/18)m/

Time =18s

Time =Distance/speed

18=X+180/(300/18

18×300=18(X+180)

300=X+180

x=300-180=120

so length of the train=120m

Answer 2

Answer:

look down

length of train = x

length of platform = 180

full distance = x + 180

speed = 60 km/h = 60 × 5/18 = 300/ 18

time = 18 second

formula = time = distance /speed

18 = x + 180 / 300 / 18

300 × x + 180

x =300 - 180 = 120m
