Lin ride her bike 20 miles in 15 minutes. If she rode at constant speed what is the unit rate and how do you know ?

Varvara68 [4.7K]

$v=\frac{d}{t} \ \ \where: v=spped \ \ \ d=distane \ \ \ \ t=time\\
\\
\boxed{v=\frac{20 \ mi}{\frac{1}{4} \ h}=20*4=80 \ mi/h}$

One of two complementary angles is 4 degrees more than the other. Find the angles. (Recall that complementary angles are angles

emmasim [6.3K]

$\displaystyle \\ 
\alpha + \beta = 90^o \\ 
\alpha - \beta = 4^o \\ 
\texttt{----------- } + \\ 
2\alpha ~~/~= 94^o \\ \\ 
\alpha = \frac{94}{2} = \boxed{47^o}\\ \\ 
 \beta = 90 -\alpha = 90 - 47 = \boxed{43^o}
