Answer 1

Answer:

Its speed is 10m/s and 36km/h

Answer 2

Answer:

10m/second,14.5km/h

Explanation:

first find the speed in km/h

distance=54km

time=90minutes=90/24=3.75hrs

speed = distance /time

= 54/3.75=14.4km/h

now , find speed in m/second

1 km=1000metre

54km=54×1000m=54000metre

1minute=60second

90minutes=90×60=5400second

now,find speed

speed=distance/time

=54000/5400

=10metre/second
