Answer:

388.8

Explanation:

108*60*60(per hour to per secound)=388800

v=velocity

s=distance

t=time

v=s/t

vt=s

388800*1=388800

388800/1000(km to metres)=388.8

Hi,
The length of the building in meters is 30 meters
How I got my answer:
Convert kilometres into meters.
To covert to meters from kilometres, multiply with 5/18
108 Km=(108*5/18)m
108Km=30m/s
time=1 sec speed=30m/s d=?
d=s*t
d=30*1
d=30 meters
Length of the building in meters is 30 meters.
Hope this helps you.
