Here average speed for given motion is defined as ratio of total distance covered by total time
so here we can say
here total distance can be calculated by formula
distance = speed * time
here given that its average speed is v = 2.05 m/s
for first half let the time is "t " seconds and the speed for that is 2.01 m/s
and for next half time will be same and it is "t " seconds again
so by plug in all data in above equation we have
so its speed for next half must be 2.09 m/s
