total height of building=28×5=140m
the man is at 50m from ground
so, it is from 65m from basement
at 2 floor from basement=5m
so,
total distance=65-5=60m
speed of lift=1m/s
time=distance/speed= 60/1=60s=1min
the man is at 50m from ground
so, it is from 65m from basement
at 2 floor from basement=5m
so,
total distance=65-5=60m
speed of lift=1m/s
time=distance/speed= 60/1=60s=1min
