Laura will go for a run during her lunch break if the temperature is between 60^\circ\text{f}60 ∘ f60, degree, f and 80^\circ\text{f}80 ∘ f80, degree, f. the average speed, sss, in miles per hour, at which laura runs is dependent on the temperature, ttt, in degrees fahrenheit (^{\circ}\text{f})( ∘ f)left parenthesis, degree, f, right parenthesis, at the start of her run and can be modeled by the function s(t)=6+0.1(80-t)s(t)=6+0.1(80−t)s, left parenthesis, t, right parenthesis, equals, 6, plus, 0, point, 1, left parenthesis, 80, minus, t, right parenthesis. the distance, ddd, in miles, that she can run in 303030 minutes given that her average speed is xxx miles per hour can be modeled by the function d(x)=0.5xd(x)=0.5xd, left parenthesis, x, right parenthesis, equals, 0, point, 5, x.
