Answer:
6 minutes
V1=100m/min
time taken= 24min
total distance D=V*T
100*24=2400
NEW SPEED V2=80 m/min
DISTANCE=2400
TIME TAKEN=2400/80=30 MINUTES
EXTRA TIME=30-24= 6 min

6 minutes
explanation:-
we know, distance/velocity=time
here-
In 1 minute Eliza covers 100 meters distance
Then in 24 minutes Eliza covers 2400 meters distance
So total distance is 2400
After being slower Eliza's velocity=100-20=80m/min
Now the total time should be taken to cover the distance is=2400/80=30min
Then the rest time is=30-24=6 min
