Answer:
It can cause headaches and pains at a close distance. It depends how big the monitor / TV.
Explanation:
For example if you sit close to a Television that's 60 inches or so, you most likely will get a headache but only after many hours spent watching.
or 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.
Let x represent the total length of the board so as to allow for the cutting of 5 lengths.
Since each length needed to be cut is 234 feet, hence:
x = number of lengths × feet per board
x = 5 lengths × 234 feet
x = 1170 feet
Hence for 5 lengths of 234 feet to be cut from a board, the board must have a length of at least 1170 feet.

The Winter Olympics are held every 4 years.
The distance between the campsite and the rest area is 9 miles.
The given parameters:
- <em>Initial speed of the campers, u = 4.5 mph</em>
- <em>Final speed of the campers, v = 4 mph</em>
<em />
Let the time of motion from the campsite to rest area = t (hours)
Time for return trip = t hours + 15 mins
= (t + 0.25) hours
Let the distance between the campsite and rest area = d
d = 4.5t
d = 4(t + 0.25)
4.5t = 4(t + 0.25)
4.5t = 4t + 1
4.5t - 4t = 1
0.5t = 1
t = 2 hours
The distance between the campsite and the rest area is calculated as follows;
d = 4.5t
d = 4.5 x 2
d = 9 miles
Thus, the distance between the campsite and the rest area is 9 miles.
