Class 5? I’m not really sure what the question is
Step-by-step explanation:
gfyiaycoeayclpb tydivh.
<span>So ball A (100 feet) will hit the ground after 2.49 seconds and ball B (75 feet) after 3.15 seconds</span>
Circumference = πD
π*49 = 153.94 (We can leave it as it is because there are two halves to the circle on either side of the training track)
81*2 = 162 (There are two 81 meter lines)
153.94+162 = 315.94m
The length of the training track is 315.94m
Hope this helps! :)
