Answer

<p> Mean(speed) = distance/time = 330m/60s = 5.5 m/s </p>.

Explain

<p> Speed is the rate at which an object (or person, in this case) travels over a designated distance. Average speed is defined as the total distance traveled by an object divided by the elapsed time to cover that distance. Here, Miss Blake runs a total distance of 330 metres in 60 seconds. We need to use the formula for calculating speed, which is "speed = distance / time". In this case, the speed is unknown, the distance in metres is 330 and the time in seconds is 60. We insert all these numbers in our speed formula and do the simple math calculation to determine Miss Blake's average speed in metres per second.</p>
