66cm is equal to 6.6e+8 nanometers.
Keeping in mind that "dx" is the delta x, or differential over the x-axis, whilst "dy" is the delta y or differential over the y-axis,
1 inch= 2.54
6 inch= 15.24 becuase 2.54*6=15.24
Hope this helps!!
12s, you don’t have a value for s, so the problem can’t be fully solved but if you did you would multiply 12 by her speed
Hope this helps
