Laura will go for a run during her lunch break if the temperature is between 6 0 ? f 60 ? f and 8 0 ? f 80 ? f. the average speed, s s, in miles per hour, at which laura runs is dependent on the temperature, t t, in degrees fahrenheit ( f ) ( ? f), at the start of her run and can be modeled by the function s ( t ) = 6 + 0 . 1 ( 8 0 ? t ) s(t)=6+0.1(80? t). the distance, d d, in miles, that she can run in 3 0 30 minutes given that her average speed is x x miles per hour can be modeled by the function d ( x ) = 0 . 5 x d(x)=0.5x. find an explicit expression that models the distance that laura runs in 3 0 30 minutes given that it is t ? f t ? f outside at the start of her run.
