Journey 4008

Hansel has a step length of 75 cm, and his little sister Danka is only 60 cm. How many steps does Danka take to school if Jan walks 820 steps? How many steps does their father take on the same journey? Who walks 4.5 m in 5 steps?

Correct answer:

D =  
o =  683

Step-by-step explanation:

$$\begin{gathered} s=0.75\cdot 820=615 \\ D=s/0.60=615/0.60=1025= \end{gathered}$$

$$\begin{gathered} k=4.5/5=\frac{9}{10}=0.9 \\ o=s/k=615/0.9=683 \end{gathered}$$
