of 95 km/h. What was the average speed for the remaining
journey?

then i can tell u the segment where the

average time interval starts degrading is the segment where the car is slowing down

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
