A. 600
B. 2500
C. 3600
D. 5000
Answer: Option C
i think answer should be 3601. Because distance between two pole is 50m i.e 1 pole must be added with.
A train crosses 161 telegraph posts situated at a distace of 11 yards each in one minute what is the speed of train in miles per hour
c 3600
Distance travelled in 4 hrs. 45*4= 180km.
ie 180000m. No. poles 50 metres apart 180000/50 = 3600
