Question

100 metre lambi ek train 48 km per hour ki speed se chalti hui ek aadmi ko 8 second me par kar jati hai aadmi ke chlne ki gati kya hogi

Answer 1

Answer:

48kmph

Step-by-step explanation:

100m ka distance cover karne k liye train ko itna samay lagega

d=s*t

100=(48*1000/3600)*t

t=3600/480

t=7.5 sec

lekin aadmi se aage Jane k liye train ko lage 8 seconds

toh distance covered by train in 8 seconds is

d=(48*1000/3600)*8

d=106.677m

ab train ko aadha second jyada laga matlab aadmi bhi train ki disha main aage badh raha tha aur aadhe second mein usne 6.667m cover kiya

so uski speed hai

s=6.667/0.5

s=13.334m/s

s=48kmph
