How to solve Related to Velocity in Physics Radha cover 4.5 km distance in 12 min on cycle find her speed in km/hrSolve ForKnown 1 Identify knowns & unknowns This question is asking to find average velocity with knowns of displacement and change in time. 2 Identify the related formula This is the formula used for problems related to Velocity. \(\xpmhighlightbox{bgcolor=#D8F8FF, underlinecolor=#00758C, linestyle=dashed}{v}\, =\frac{\xpmhighlightbox{bgcolor=#F3E8FD, underlinecolor=#6232EC}{x}\, }{\xpmhighlightbox{bgcolor=#F3E8FD, underlinecolor=#6232EC}{t}\, }\) \(v\) = average velocity \(x\) = displacement \(t\) = change in time 3 Input variables, solve and simplify Identify knowns\(x=4.5~\mathrm{km}\\ t=12~\mathrm{min}\)Plug-in values\(v=\frac{4.5~\mathrm{km}}{12~\mathrm{min}}\) Divide the numbers \(v=\bm{0.375~}\mathrm{km}\bm{/}\mathrm{min}\) 4 Check unit of measurement velocity is measured in kilometer per minute. Solution \(v=0.375~\mathrm{km}/\mathrm{min}\)

Verified answer
Answer:
time taken=12min
distance covered =.5km=4500m
speed=distance covsred/time taken
speed=4500/12=375m/s
in km/h
distance =12m=12/60=0.2 h
speed=4.5/0.2
speed=22.5km/h ans.
