Step-by-step explanation:

Answer 2

The average speed of Luis for the entire trip from home to the hardware store and back=12mph

Step-by-step explanation:

Speed of Luis when he travel from home to hardware store=$v_1=8mph$

Time =$30minutes$

Speed of Luis when he traveled back home  along the same path =$v_2=24mph$

We know that average speed formula:v=$\frac{2v_1v_2}{v_1+v_2}$

Using the formula

$v=\frac{2\times 8\times 24}{8+24}$

$v=\frac{384}{32}=12mph$

Hence, the average speed of Luis for the entire trip from home to the hardware store and back=12mph
