Question

During track practice, Avery runs 8 laps around the track. One lap around the track equals 400 meters (m). ________kilometers (km) Avery runs during practice.

  1. 3.2    
  2. 32    
  3. 0.32    
  4. 320    

Hint:

1lap = 400m
km =kilometer
m = meter
1km = 1000m

The correct answer is: 3.2


    Converting the laps into meter
    1 lap around the track = 400m
    So, in 8 laps = 400 × 8
    = 3200 m
    Converting the m into km
    Now, 3200 m = fraction numerator 3200 over denominator 1000 end fraction = 3.2km
