Ready4	For the first portion of her trip, Frederique traveled $\frac{x}{8}$ of the total distance in miles at an average speed of 40 miles per hour, such that $1\leq x \leq 7$ . She traveled the remaining distance at an average speed of 60 miles per hour. In terms of $x$ , what was Frederique's average speed for the entire trip?
Ready4	How quickly heat transfers through an insulating layer depends on that insulator's thermal resistance. If two insulators are used together, the inverse of the combined thermal resistance is the sum of the reciprocals of each layer's thermal resistance. If the thermal resistances of two insulators are $r$ and $2r$ , what is their combined resistance?
