Case 5: object is between F & P Concave mirror C P virtual & erect magnified behind mirror

I'm having trouble completing the problem I've attached a picture of below. I was able to find the the Earth's average speed in m/s relative to the sun by doing (2pi*(1.49x10^11))/31536000. But I am struggling to find the average velocity for the same thing over a period of one year in m/s. I was wondering how to calculate that? I've tried doing the (final velocity-initial velocity)/2 but the program doesn't accept my answer when using that approach.

Write the scientific notation (10n) 0012 = 560000 =             Write out the number 3 x 104 = 8 x 10-2 =   How many centimeters are in 2 kilometers? Write your answer in scientific notation.                 How long would it take in minutes to travel 5km if you are traveling at a speed of 30 m/s?                 A ship left shore 3 days ago and has been moving at a constant speed. The cruise ship is now 1440 miles away. What is the average speed in mph?                       5a. A tuning fork has a period of 4s. What is the frequency?             5b. If the tuning fork above is struck in air, what is the wavelength?               5c. If the tuning fork above is struck in water, what is the wavelength?               The wave below is traveling at 5 m/s.   6a. What are the wave y(x) and oscillator y(t) sinusoid equations for this wave?           What is a sound wave?                 Identify where the compressions and the rarefactions are in both graphs.…

You start out by driving 176 miles north in 2 hours and 26 minutes, and then you stop and park for a while. Finally you drive another 134 miles south in 3 hours and 38 minutes. The average velocity for your entire trip was 5.54 miles per hour to the north. How much time did you spend parked? 1 hours 30 minutes 3 hours 1 minutes 0 hours 45 minutes 7 hours 34 minutes

Express Newton's second law in symbol form? need full explanation to understand

The distance between two cities is 328 km. Using your knowledge that 1 mile is equivalent to 1.609 km, convert this distance to miles.

Which formula did you use for this? I'm too slow to catch up on it. My bad.
