In an ANPR system the time that a vehicle passes a monitoring point is recorded. A suspicious vehicle can be tracked along the motorway by noting the time it passes each ANPR monitoring point. If a car passes monitor A at 22.12.06 and monitor B at 22.54.07 and the monitors are 62 km apart calculate the average speed of the vehicle between the two monitoring points. Express your answer in km/hour to 2 decimal places.

  • math - ,

    monitor A 22:12:06
    monitor B 22:54:07
    diff. = 42:01

    42 min 1 sec = 42 + 1/60
    42 min 1 sec = 42.01667 min
    42.01667/60 = 0.700278 hr

    R = D/T
    R = 62/.700278
    R = 88.53627 km/hr
    R = 88.54 km/hr

    check
    D = RT
    D = 88.54 x .70
    D = 61.978
    62 = 61.978
