Question

In a race of 300m Mohan complete it in 40s find his speed 8n km /h

Answer 1

Answer:

Distance mohancover=300m

time he take to cover=40s

so speed formula=

\frac{d}{t}

\begin{gathered}therefore \\ = \frac{300m}{40s} = 7.5m |s\end{gathered}

so the speed of mohan is 7.5m/s

you want answer in km/hr

so 1m=1/1000km

and 1sec=1/3600hr

so to convert it into km/hr multiply 7.5m/s by the above equation
