Question

С какой скоростью семья ехала на велосипедах,если за 1 ч они 3 раза объехали парк по периметру? ширина парка 870м длинна 1130 м

Answer 1

1) 1130 + 870 = 1900
2) 1900: 3 =??

Answer 2

Calculating the Speed of the Family on Bicycles

To calculate the speed at which the family was traveling on bicycles, we can use the information provided about the park's dimensions and the number of times they circled the park in one hour.

Given: - Width of the park = 870 meters - Length of the park = 1130 meters - They circled the park 3 times in 1 hour

We can calculate the total distance covered by the family in one hour by adding the distances covered in each circle.

Total distance covered in one hour = (3 * perimeter of the park)

The perimeter of a rectangle is given by the formula: 2 * (length + width)

Calculation

Total distance covered in one hour = 3 * (2 * (1130 + 870)) meters

Total distance covered in one hour = 3 * (2 * 2000) meters

Total distance covered in one hour = 3 * 4000 meters

Total distance covered in one hour = 12000 meters

Now, to find the speed, we can divide the total distance covered in one hour by the time taken.

Speed Calculation

Speed = Total distance covered in one hour / Time taken

Speed = 12000 meters / 1 hour

Speed = 12000 meters per hour

Therefore, the family was traveling at a speed of 12000 meters per hour on their bicycles.
