>>>> Where John is going!! :)

Verbal Model Distance= Rate x Time

Labels Distance =42(miles)

Rate=r(miles per hour)

Time=1.55(hours)

Algebraic Model 42=r(1.55)


42/1.55=r (Solution*) You can use the formula d=rt to write a verbal model!!


27~r

-The car's average speed is about 27miles per hour.


Answer= 42miles~ 27Miles/hour X 1.55 hours
