Solution
[tex]Speed\text{ = }\frac{distance}{time}[/tex][tex]\begin{gathered} Speed\text{ =4km/h} \\ Time=15minutes=\frac{15}{60}=\frac{1}{4}=0.25hour \end{gathered}[/tex][tex]\begin{gathered} 4=\frac{Distance}{0.25} \\ \\ Distance=\text{ 4}\times0.25 \\ Distance=\text{ 1km} \end{gathered}[/tex]1km is 100, 000cm
[tex]\frac{100,000}{62.5}=1600[/tex]The final answer
1,600 steps
