It took the race car 22 minutes to travel 114.4 kilometers. at what rate did the car travel? use the formula r=d/t where r is the rate, d is the distance, and t is the time. round your answer to the nearest tenth.

5.2 Km/Min

Step-by-step explanation:

Speed/Rate= Distance/Time

Speed/Rate = 114.4/22

Speed/Rate = 5.2 KM/min

5.3 km/min

Step-by-step explanation:

Distance = 114.4 kilometers

Time = 22 minutes

Rate = 114.4 km /22 min

Rate = 5.2 km/min

step-by-step explanation:

pentagon

step-by-step explanation:

the coordinates   a(5, -2), b(3,-1),c(-4,-4) d(-3,8) and e(-1,4) forms the vertices of the polygon when they are connected in order.

in order to classify that which polygon is it with the given coordinates, first count the number of vertices and then count the number of sides it can make with these vertices.

since, the given coordinates have five vertices, therefore, it will make five sides. moreover, pentagon is regular in nature therefore it will be convex.

now, a polygon with five sides is known as pentagon, therefore, the given polygon is the pentagon.
