Given:
Perimeter of a football field = 920 feet.
The width is 60 feet more than one-third of the length.
To find:
The dimensions of a football field.
Solution:
Let the length of the field be x.
Then, width =
We know that,
Subtract both sides by 120.
Multiply both sides by 3.
Divide both sides by 8.
Now,
Therefore, the length and width of the football field are 300 feet and 160 feet respectively.
15 mins = 900 s
We need to find all common multiples of 18 and 42 less than or equal 900.
We'll find the least common multiple first.
18|2
9|3
3|3

42|2
21|3
7|7
Now, we nned to find all multiples of 126 that are less than or equal 900.
Those are 126,252,378,504,630,756,882. There are 7 of those.
Therefore the answer is 7.
