Answer:

450meters

Step-by-step explanation:

Given data

Speed = 81km per hour

Let us convert to meter per seconds

1 km= 1000m

1 hour=3600 seconds

= 1000/3600= 5/18 m/s

=81*5/18

=405/18

=22.5 m/s

Hence the distance traveled in 20 seconds is

distance= speed*time

distance= 22.5*20

distance= 450 meters

Hence the distance is 450meters
