Question

Each lap around The track is 400 meters .A. How many laps does someone run if they run 2 laps , 5 laps , x laps .

Answer 1

Each lap around the track is 400 m.

Therefore, if someone run 2 laps, we have,

$400\times2=800m$

Similarly, when someone runs 5 laps, we have,

$400m\times5=2000m$

Therefore when someone runs x laps,

$400m\times x=400x\text{ m}$

When x= 1,

$400m\times1=400m$
