Well if u see here the graph is showing us 1.5 on the graph so we multiply that by 6 and we get 46 as our final anwser

Answer:
2.67m/s
0.67m/s
Explanation:
Given parameters:
Number of laps run = 2.5laps
time taken = 75 sec
Diameter of track = 50m
Circumference = 120m
Unknown:
Average speed of runner = ?
Average velocity of runner = ?
Solution:
Average speed depends on the total distance traveled, it is the rate of change of distance with time. It covers the full extent of the path;
Average speed = ![\frac{distance}{time}](https://tex.z-dn.net/?f=%5Cfrac%7Bdistance%7D%7Btime%7D)
distance = circumference
Average speed =
= 2.67m/s
Average velocity depends on the displacement at the end of the particular journey. The displacement deals with the length of path from start to finish in a specific direction.
The diameter is the same as displacement here.
Average velocity =
=
= 0.67m/s
