Kerry skates laps around the playgroung.
The playground is 150 meters long and 50 meters wide.
How many laps will it take her to skate 1 kilometer?
I need els really badly and I av a math test tommorow I need to study perimeter and area.... I old appreciate ur help. Tnx😊
150 + 50 + 150 + 50 = 400 meters = 0.4 km
.4 km/lap * n = 1 km
n = 1/.4 = 2.5 laps
150 + 50 x 17 = 1000 (1 km)
131,5m long and55,7m wide calculate how many laps it will take to run a total of 1km
P = 2W + 2L
P = 300 + 100
P = 400 meters
1 km = 1000 m
1000 / 400 = ?
To find the number of laps it will take Kerry to skate 1 kilometer around the playground, we need to calculate the total distance she skates for one lap, and then divide 1 kilometer by that distance.
First, let's find the distance Kerry skates for one lap. Since she skates around the perimeter of the playground, we need to calculate the perimeter.
The perimeter of a rectangle is given by the formula P = 2 * (length + width).
In this case, the length of the playground is 150 meters and the width is 50 meters. So the perimeter of the playground is P = 2 * (150 + 50) = 2 * 200 = 400 meters.
So, Kerry skates a distance of 400 meters for one lap around the playground.
Now, let's convert 1 kilometer to meters. Since 1 kilometer is equal to 1000 meters, we can substitute this value into the equation.
Number of laps = (1 kilometer) / (distance per lap)
= 1000 meters / 400 meters
To simplify this calculation, we can divide both the numerator and denominator by 100 meters.
Number of laps = (1000 meters / 100 meters) / (400 meters / 100 meters)
= 10 / 4
= 2.5 laps
Therefore, it will take Kerry approximately 2.5 laps to skate 1 kilometer around the playground.
Keep in mind that this answer assumes that Kerry skates exactly along the perimeter of the playground and there are no additional factors affecting the distance she covers.
