Final answer:
The student's question touches on several aspects of mathematics, including algebra, physics equations, and practical arithmetic tasks. A step-by-step approach and further clarification of the context for each equation or scenario may be needed to provide a clear solution.
Step-by-step explanation:
The question seems to relate to multiple separate problems in mathematics, requiring an understanding of equations and substitution to find the values of variables, as well as applications to real-world scenarios like converting map scales to actual distances and measuring ingredients for recipes. The question might be asking for help with algebra, physics equations, or practical arithmetic calculations.
At first glance, without additional information or context for each of the provided equations and scenarios, it is not possible to determine the exact methods for solving each one. A step-by-step approach would involve clarifying the relevant equations and constants, solving for the missing variable by substituting known values, and conducting unit conversions where necessary.
