Question

Arrange the following in descending order. Posted Speed Limit > Time Mean Speed - > Space Mean Speed

Answer 1

Teme mean speed - Teme mean speed is Space mean Speed a measured al point pasticular - Measuring of space mean speed is related average of spot speads average of to length of roadway harmonic mean of Spot Speeds It is found by travel distance/ - It is vehicle speeds passing on by average travel on particular point Roadway during fixed interval of time time. n ū=hu ū= E the u. where a,,U2.. are Spot speeds and observahon n is no: of Teme speed is always greater than Space mean speed as tine speed is of average spot spads and space moan speed is harmonic moan.

It is Posted speed :- It is the speed limit. marimum speed that is permitted on As it is limit. It is always a roadway the greatest The order in which the above speeds lange can be elluspoated using problem. If the spotspeeds 60, 40, 55, 45, then fend the time mean speed and space mean spead. are Speed limit is 70 Time mean speed GO+40 +55 +45 Eu = 4 50 n Space - mean speed u tu. u.

4 48.73 = - + + LL 55 + 60 40 45 Posted speed limit = 70 70 > 50 148.73 Hence, it is concluded that Posted speed limit > Time mean speed > Space mean Speed
