First journey: 1 hour; second 2½ hours; third 1¼ hours and fourth 2 hours. Total 400 miles in 6¾ hours = 59¼ mph, (actually 59.259259)
To work it out, you have to bear in mind that each time you travel 100 miles. If it is going a hundred miles per hour, it will take an hour. All you have to do is alter the speed so it goes to a hundred for example: If you double 40 you will get 80 which takes two hours but still doesn't reach a hundred miles. The, as you need 20 more, you half 40 and add it on bringing the total time to 2 and a half hours.

Explain in a physics way how to find the average speed for a trip in your car?
To find the average speed for a trip in your car, you would calculate the total distance traveled and divide it by the total time taken. This would give you the average speed at which you traveled throughout the trip. It is important to note that this average speed may not accurately reflect your actual speed during specific parts of the trip if there were varying speeds or stops.

If you want to go an 80 kmph average velocity on a trip and you go 57kmph on the first half how fast do you need to be going the second half of the trip to reach the 80kmph average and explain?
Assume any distance. The calculation is the same for any distance, so you can either assume a distance, or use a variable such as "d" for the distance. Calculate how long the trip should take in total, and how much time you spent on the first half. Then use the remaining time for the remaining distance. For all of these calculations, the basic formula is: distance = speed x time.

Mercury has an average distance to the sun of 0.39 AU. In two or more complete sentences explain how to calculate the orbital period of Mercury and then calculate it.?
According to Kepler's law, the expression P2/a3 is approx equal to 4pi2/GM where P = period,a = average orbital distance = 0.39 AU = 58,343,169,871 metresG = universal gravitational constant = 6.67408*10^-11 m3 kg-1 s-2M = mass of the Sun = 1.989*1030 kilograms.Substituting these values into the expression and solving givesP2 = 59061382597774 seconds2 which implies that P = 7685140 seconds. This equals 88.9 Earth days.
