In the previous problem, we calculated how much fuel the truck driver had after adding 21/36 gallons and 26/42 gallons to 9 original gallons. 

Suppose now we mistakenly thought that the second stop was dispensing fuel faster and he actually added 26/4 gallons instead of 26/42 gallons in the second stop. If he still had the original 9 gallons to start with and added the 21/36 gallons in the first stop as per the original scenario, how much fuel would the truck driver have now in his truck after making both stops?
