# I have to pass this class with a B or I will not graduate.

Hi I am needing help with this lab for astronomy. I have to pass this class with a B or I will not graduate. I currently have a 79 in the class I need help

getting the correct answers for this lab.

My professor stated "Hello Stephanie, Your plot is not quite correct. You seem to be plotting the velocity correctly but the distance values are not plotted in the right place. For instance at the top your 41000 km/sec data point should be at a distance of 210.1x10^20 km. Yours is nearer 110? Then when you do the calculations you have forgotten to to include the x10^20 km in the bottom of your slope fraction. Then in 2 you should simply divide the value you get for H from Q1 into 1. As I said in the instructions and announcement do not use the 'accepted' value for H from the text book or my slides use the value you calculated in Q1."

Thank you!
