Mai runs 3 laps around the track in 4 minutes.
a. How many minutes per lap is that?
b. How many laps per minute is that?
C. . If Mai runs 21 laps at the
same rate, how long does it
take her?
Explain your reasoning


Sagot :

The total distance Mai runs is 400(4), so the distance equals 1,600 meters. If it takes her 250 meters per minutes, then if you divide 250 with 1600– it’ll take her 6.4 minutes
