Mai runs around a 400 meter track at a constant speed of 250 meters per minute. How many minutes does it take Mai to complete 4 laps of the Track?

Answer :

Answer:

6.4 minutes, or 6 minutes and 24 seconds

Step-by-step explanation:

She is running 4 laps, so she is running 1600 meters total.  If she runs 250 meters per minute, divide 1600 by 250 to determine how many minutes it will take...

1600/250  =  6.4

Which is 6 minutes + 0.4 minutes          

*there are 60 seconds in a minute, so the 0.4 represents 40% of another minute.  Multiply 60 by 0.4 to see how many seconds this is...

(0.4)60  = 24 seconds,

So she ran the laps in 6 minutes and 24 seconds
