Question

One lap of a racetrack is equal to 1 . A runner completes 15 laps in an hour. What is his speed and

velocity?

Answer 1

• Distance=15laps=15(1)=15km
• Time=1h
• Displacement=0(As it comes back to starting point)

Speed:-

`\\ \tt\hookrightarrow (Distance)/(Time)`

`\\ \tt\hookrightarrow (15)/(1)=15km/h`

Velocity:-

`\\ \tt\hookrightarrow Displacement/Time`

`\\ \tt\hookrightarrow 0/1=0km/h`
