Question

Peter is running laps around a circular track with a diameter of 100 meters. If it takes Peter 12 minutes to run 4 laps, how quickly is he running (in meters per second)?

Answer 1

Answer:

v = 1.74 m/s

Explanation:

Given that,

Diameter of a circular track, d = 100 m

Distance covered for the 4 laps,

$D=4\pi d\\\\D=4\pi \times 100\\\\D=1256.63\ m$

Time, t = 12 minutes = 720 s

We need to find the velocity of the peter. It can be calculated as follows :

$v=\dfrac{D}{t}\\\\v=\dfrac{1256.63\ m}{720\ s}\\\\v=1.74\ m/s$

So, the speed is running with a velocity of 1.74 m/s.
