1.	18. A train 280 m long is moving at a speed of 60 km/hr. What is the time taken by it tocross a platform 220 m long?
Answer» Total distance to cover = 280 + 220 =500 m= 0.5 km Time = distance /speed = 0.5 (km) /60 (km/hr) = 0.0083333333. Hour In minute, = 0.008333*60 Time = 0.5 minutes In seconds, Time=30 seconds. 280+220=500 is the total distancespeed=60 km/htime=distance/speedtime=.500/60=.00833h =.5 min =30 sec

Answer»

Total distance to cover = 280 + 220 =500 m= 0.5 km

Time = distance /speed = 0.5 (km) /60 (km/hr) = 0.0083333333. Hour

In minute, = 0.008333*60 Time = 0.5 minutes

In seconds, Time=30 seconds.

280+220=500 is the total distancespeed=60 km/htime=distance/speedtime=.500/60=.00833h =.5 min =30 sec
