Solution:
As we given that 
then using this conversion factor we can write 
and further it can be written as
Hence the required conversion factor is 2.54 cm/1 inch as we can see from the above calculation.
Well all you need to do is add them so 3.45 + 2.2 = 5.65 then add 0.055 to 5.65 which is 5.705 and last but not least, add 9.03 to 5.705 which is 14.735 which makes 14.735 how many miles she ran. Hope this helps
It will take them a total of 3.07 hours.
