Answer:
AB = 20 metres
BC = 60 metres
Step-by-step explanation:
Let AB = x
Then, BC = 3x
<u><em>Condition:</em></u>
=> x+3x = 80
=> 4x = 80
Dividing both sides by 4
=> x = 20
So,
AB = 20 metres
BC = 3(20)
BC = 60 metres
How many class members are there??
Do you know the length and height of the field? If you do, all all the sides together (Height + Height + Length + Length) and you get the answer to Part A.
Part B:
Just do 120 times 5. Then, divide your answer by 6. The answer will be the time they need to run each lap in.
Part C:
Again, what is the length? When you know your length, divide it by 2. Your answer is the side length.
Hope that helped. :)
