john ran around a rectangular field 180 m long and 60 m wide 6 times
in 12 minutes. find his speed in m/min.

240 m/minute

Step-by-step explanation:

Find the perimeter of the field and then multiply that result by 6, to find the total distance John ran:

6P = 6(2·180 m + 2·60 m) = 2880 m

Then his average speed was

2880 m

= 240 m/minute

 12 min

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
