Question

270 मी लम्बी रेलगाड़ी 30 मी/से की चाल से 180 मी लम्बे पुल को
कितने सेकण्ड मे पार कर जायेगी?​

Answer 1

Answer:

15 sec

Explanation:

length of pool = 180 m

length of railway = 270m

total distance to be traveled = 180+270

total distance to be traveled = 450m

time required = total distance/ velocity

time required = 450/30

time required = 15 sec
