Question

rohan cycles 25m in 10 seconds.Find the speed in km/hr​

Answer 1

$\purple{ \mathtt{ \underline{ \huge{ \fbox{ \orange{ \: Solution \: \: : }}}}}}$

Given ,

Distance = 25 m

Time = 10 sec

In terms of kilometer and hour

Distance = 25/1000 = 0.025 km

Time = 10/3600 = 0.0027 Hr

We know that ,

$\sf \star \: \: \mathtt{ \large{\fbox {Speed = \frac{ Distance }{Time} }}}$

Substitute the values , we get

$\hookrightarrow \sf Speed = \frac{0.025}{0.0027} \\ \\ \hookrightarrow \sf Speed = 9.25 \: \: km/hr$

Hence , the speed is 9.25 km/hr
