convert speed to m/s==> 60 *5/18 = 50/3 m/s
distance(length of train)=speed *time => 50/3 m/s *10 s=>500/3 m

60 km in a hour
1 km in a minute
in 10 seconds 1000m/6=500/3

60 km/hr=(60*1000)/(60*60)m/sec=(50/3) m/sec
in 10 sec = (50*10)/3= 500/3 meter
Ans is option 1

speed=60km/hr=60*(5/18)=(50/3)m/s
t=10s
length of train=(50/3)*10=500/3metre

Vinay Sipani 11 years AGO

distance travelled = length of train = L
Time taken = 10 seconds
speed = 60 kmph = 50/3 m/s

=> L = 10 * 50/3 = 500/3 m

v=s/t
s=v*t
v=60km/hr=60*5/18=50/3
s=50/3*10=500/3

Anurag Arora 11 years AGO

speed = distance/time
s = 60 km/hr
s = 60 * 5/18 = 50/3 m/sec
dis = speed * time
dis = 50/3 * 10 = 500/3m(as pole is a point object so there is no need of taking its length into consideration)
