Kerry states laps around the playground. The playground is 150 m long and 50 m wide. How many laps will it take Kerry to skate 1 km?
No, it's 2.5 laps.
1 km= 1000 m
1 lap= 400 m
400x2= 800
Half of 1 lap= 200 km
So 2 laps and a half.
perimeter=2(150+50)=400m
number laps=1000/400 so he has to do three laps.
It's 6.2 laps duh
how did you got that
To find the number of laps Kerry will need to skate to cover 1 km, we need to calculate the total distance she covers in one lap and then divide 1 km by that distance.
The perimeter of the playground is calculated by adding up the length of all the sides. In this case, the length of the playground is 150 m and the width is 50 m. So, the perimeter is given by:
Perimeter = 2 * (length + width)
= 2 * (150 m + 50 m)
= 2 * 200 m
= 400 m
Now we know that Kerry needs to skate 400 m to complete one lap around the playground.
To find out how many laps are required to cover 1 km (which is equal to 1000 m), we can divide 1000 m by 400 m.
Number of laps = 1000 m / 400 m
= 2.5 laps
Therefore, Kerry will need to skate 2.5 laps around the playground to cover 1 km.
