Answer 2

Answer:

In $\frac{3}{4}$ hour is (60 * 45) seconds = 2700 seconds. The light flashed every 6 seconds. In 2700 seconds $\frac{2700}{6}$ = 450 times. Counting starts after the first flash, the light flashes 451 times in $\frac{3}{4}$ hour.

Explanation:

In $\frac{3}{4}$ hour is (60 * 45) seconds = 2700 seconds. The light flashed every 6 seconds. In 2700 seconds $\frac{2700}{6}$ = 450 times. Counting starts after the first flash, the light flashes 451 times in $\frac{3}{4}$ hour.

Flashes of light are pins or spots of light that you see in your field of vision.  The flashes of light in your vision come from your eye.

Most flashes occur when the vitreous gel inside the eye shrinks or changes and pulls on the retina (the light-sensitive lining of the eye). Flashes of light can also occur if you get hit in the eye or rub your eyes too much. In both cases, flashes are caused by a physical force on the retina

There are usually flashes of light and then they disappear quickly. In contrast, bright spots, lines, or spots that appear and stay in place for a period of time may be a migraine aura or a symptom of another condition. A migraine aura can look like shimmering jagged lines or appear undulating, like heat waves. A migraine aura can occur even when you don't have a headache

Light rays or halos that you may see around lamps, headlights or street lights may be a symptom of cataracts or the effect of an intraocular lens (IOL) or refractive surgery.

Many people will see occasional flashes of light, especially as they get older. These occasional flashes are usually harmless, but should be discussed with your ophthalmologist during an eye exam. However, if you suddenly start seeing repeated flashes of light, it could be a serious problem, especially if you also have cloudy floaters (gray or dark spots that move back and forth in your vision) or vision changes.
