Answer 2

Given;

`10.49seconds\text{ for the }100meter\text{ dash}`

Step 1: Convert 100 meter to mile;

From the table, we have;

`\begin{gathered} 1000meter=1kilometer \\ \\ 100meter=0.1kilometer \\ \\ 0.62mile=1kilometer=1000meter \\ \\ 0.062mile=100meter \end{gathered}`

Step 2: Convert 10.49 seconds to hour;

`\begin{gathered} 60seconds=1minute \\ \\ 60minutes=1hour \\ \\ (60*60)seconds=3600seconds=1hour \\ \\ 10.49seconds=0.003hour \end{gathered}`

Thus, the conversion 10.49 seconds for the 100 meter dash to miles per hour is;

`\begin{gathered} mile\text{ }per\text{ }hour=(0.062)/(0.003) \\ \\ mile\text{ }per\text{ }hour=20.7 \end{gathered}`

ANSWER:

`20.7(mi)/(hr)`
