Answer:
1/3 of 6 meters is 2 meters
Step-by-step explanation:
1800 laps in 12 weeks
1800/12 = 150 laps in 1 week
150/5 = 30 laps a day
30 laps in 45 minutes
x laps in 60 minutes
x = (30*60)/45 = 40 laps per hour
Two correct answers:
9 + x
x + 9
Or you can say
x - -9
or
9 - -x

that means the equation is 30/140
that equals .2142 . . .
that moves over the 21%
