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:-

$\\ \tt\hookrightarrow \dfrac{Distance}{Time}$

$\\ \tt\hookrightarrow \dfrac{15}{1}=15km/h$

Velocity:-

$\\ \tt\hookrightarrow Displacement/Time$

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