School 6

Jirka lives 600m from the school, and Honzík 1200m. How many kilometers a week does Honzik go over Jirka on his way to school and back? How many times will more Honzík go than Jirka?

Correct answer:

a =  6 km
b =  2

Step-by-step explanation:

$$\begin{gathered} s_1=5\cdot 2\cdot 0.600=6 \\ {s}_2=5\cdot 2\cdot 1.200=12 \\ a=s_2-s_1=12-6=6\text{km} \end{gathered}$$

$b=s_2/s_1=12/6=2$
