Question

if a sprinter runs a distance of 100 metres in 9.83 seconds ,calculate his average speed in km/h

Answer 1

Answer :

Given ,

Distance = 100m

time = 9.83s

Average speed =

$\frac{total \: distance}{total \: time \: taken}$

$= > \frac{100}{9.83} \\ = > 10.17$

Now converting 10.17 in km/hour

$= > 10.17 \times \frac{5}{18} \\ \\ = > 2.825$

Thanks

Answer 2

Answer :

Answer :

Given ,

Distance = 100m

time = 9.83s

Average speed =

\frac{total \: distance}{total \: time \: taken}

totaltimetaken

totaldistance

\begin{lgathered}= > \frac{100}{9.83} \\ = > 10.17 \\\end{lgathered}

=>

9.83

100

=>10.17

Now converting 10.17 in km/hour

\begin{lgathered}= > 10.17 \times \frac{5}{18} \\ \\ = > 2.825\end{lgathered}

=>10.17×
