Question

please help! thank you!

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

Answer 1

Answer:

240m/min

Step-by-step explanation:

First we have to find the perimeter.

That can be accomplished by the following equation:

P=180+180+60+60

P=480

He ran this distance 6 times which equals 2880 m.

Divde this by 12 to get the answer:

2880/12

240

Answer: 240m/min

Answer 2

Answer:

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
