For question 1 , dont u think that if the person will run at 5 m/s once, he will have to attain 4 m/s at least once, cos speed is a continuous function in time . one can not fly to 5 m/s from 0. He will have to pass through every value of speed in the interval [0,5]. Moreover if we restrict the speed to just below 6 and have the value of acceleration (in going from 0 to 6-e m/s) modulated so as to cover 100 m in 20 sec, the answer comes out to be 'a'.

Any Thoughts......
