Solution

The correct option is A 5.556
Given:
Odometer reading, before the trip =22256 h
Odometer reading, after the trip =22356 h

So the distance travelled in the trip=2235622256=100 km

Time taken for the trip =5 h

Average speed = Total distance travelledTotal time taken

Average speed =1005=20 km h1

1 km h1=1036 m s1

20 km h1=20×1036 m s1

=5.556 m s1
