Kerry skates laps around the playground.
the playground is 150m long and 50m wide.
how many laps will it take kerry to skate 1km? explain.

So to start this off, we need to find the area of the playground. We can simply multiply 150*2 and 50*2, and we get 300 and 100. Add those together and we get 400m.
Now, we can identify the number of laps it takes. But first, we have to convert kilometers into meters. there are 1000 meters in 1 km, so we will use 1000 to find the answer
Now, we can do 1000/400 to find the answer, which is 2.5 
Therefore, it will take Kerry 2.5 laps to skate around the entire park

2.5 laps

Hope this helped!!! :D

Y=3x+1 so the first one
