The average speed in the first case is 19.86 m/s and the average speed in the second case is 13.67 m/s.
The formula of average speed is
average speed = total distance / total time
In first case
total distance is 143 km which is also 143000 m
and total time is 2 hours which is also 7200 seconds
so average speed = ( 143000 / 7200 ) m/s
average speed = 19.86 m/s
In second case
total distance is 160 km which is also 160000 m
and total time is 3 hours and 15 minutes which is also 11700 seconds
so average speed = ( 160000 / 11700 ) m/s
average speed = 13.67 m/s
