The oil lefty behind by leaking vehicles will accumulate on the road surface. When it rains, the oil will float on top of the water reducing the coefficient of friction between your tires and the tarmac. After about 20-30 min of continuous rain, there will have been enough water to generally "wash" the oils into the gutter, allowing the tread in your tire to effectively shed water from the contact surface of your tires.
The road is most slippery during the first half hour of the rain (C) because the rain mixes with the oil and dirt on the road, making it more hazardous for driving. After a long rain (A), the water washes away some of the oil and dirt, reducing the slipperiness of the road. A new road (B) typically has better traction due to the roughness of the surface.
During the first hour of rainfall after a hot dry spell.
Yes, but be aware that this is particularly bad in dry climates like Nevada. I have driven in Canadian Winters for 40 years The first 30 minutes of rain in Nevada or other desert places is worse than an ice skating rink (yes I tried it) The reason is because oils and debris form on the surface and don't get washed away on a regular basis. As the rain comes down, it tends to wash away the deposits, so it is less slippery after the first half hour of steady rain.
A:after. Do to Oil on the Roadways from leaking vehicles (oil) and or spills form chemicals containing oils. And also new roadways that have Just been paved also containing oil. Hope this Helps

Yes, it is possible for the average velocity of an object to be zero during some interval, even if its average velocity for the first half of the interval is not zero. This can occur if the object moves in opposite directions with equal distances during the two halves of the interval. For example, if a car moves 3 miles east in the first half of an hour and then moves 3 miles west in the second half of an hour, its average velocity for the entire hour would be zero.
Half-hour before sunrise to half-hour after sunset
Sydney's time, UTC+10/UTC+11, is ahead of Darwin's time, UTC+9:30. From the first Sunday of April to the first Sunday of October, Sydney is a half hour ahead of Darwin. During the rest of the year, Sydney is an hour and a half ahead of Darwin.
They will perform a half hour show to release the great first album.
Yes. Half is a noun and half an hour (half of an hour) is a time period.
The term is actually "half an hour" which is short for "half of an hour". This has same meaning as "half hour" or a rough approximation of 30 minutes.
Yes it is. It is a minor holiday on the Jewish calendar. In Israel, however, schools have a vacation.
