-Sprays with hose- DEVELOPMENT IS KEY DAMN IT, YOU MUST FOCUS ON THAT FIRST! 

Kakashi will probably have his belongings much more together than Sakura due to the volume of missions he gets sent on compared to her, so he will take half the time she takes, easily. We won't need to skip until we hit the road. Sakura can use this time to ask about the target, or what he can do to help her training as they make their way there. Since they need to be at reasonable strength he can't burn her out like he has been the past couple days, so it may come down to improving her natural attributes like speed and stamina. That and the repetition of hand seals.
