An ant travels at a constant rate of 30 cm every two minutes at what pace does the ant travel per centimeter

 1/15 min per centimeter.

Step-by-step explanation:

here, An ant travels at a constant rate of 30 cm every two minutes.

therefore speed of the ant = 30/2 = 15 cm/minute  ( since speed= distance/times)

Since, pace  means the inverse of speed.

That is If speed is measured in units of distance per unit of time thenpace is measured in units of time per unit of distance.

Thus the pace of the ant = 1/15 min/cm

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm
