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
