Apark is represented on a map with the following vertices coordinates: vertex 1 is at (−4, −1) . vertex 2 is at (−4, 5) . vertex 3 is at (2, 5) . vertex 4 is at (2, −1) . linsey jogs along the the edge of the park in order from vertex 1 to vertex 2 to vertex 3 to vertex 4 and then back to vertex 1. one unit on the coordinate grid equals 20 yd. what is the total distance lindsey jogged? enter your answer in the box.

Lindsey jogged 480 yards.

Step-by-step explanation:

The distance between two vectors, and , in which

Is given, in units on the coordinate grid, by the following formula:

So:

From vertex 1 to vertex 2

From (-4,-1) to (-4,5)

From vertex 2 to vertex 3

From (-4,5) to (2,5)

Total distance is 6+6 = 12 units

From vertex 3 to vertex 4

From (2,5) to (2,-1)

Total distance is 6+6+6 = 18 units

From vertex 4 to vertex 1

From (2,-1) to (-4,,-1)

Total distance is 6+6+6+6 = 24 units

Each unit on the coordinate grid equals 20 yards.

So Lindsay jogged 24*20 = 480 yards.

they are simplified

step-by-step explanation:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
