Quantitative Aptitude ( CCS) Time & distance

A train 280 m long is moving at a speed of 60 km/hr. The time taken by the train to cross a platform 220 m long is

30 sec.

40 sec.

60 sec.

20 sec.

Length of train = 280 m

length of platform = 220 m

total distance of ( train + platform )

= 280 + 220 = 500 m

speed of train = 60 km / hr

since ,the distance is given in ' m' so then

convert sd.from km/ hr to m/ s

speed = 60 km/ hr = 60 × 5/ 18

speed = 300/ 18 m/ s

time taken = total distance / speed

= 500 / 300 / 18 = (500 × 18 ) / 300

= 30 seconds

Hence, option 1 is the correct answer.
