Acar travels 30 1/5 miles in 2/3 of an hour. what is the average speed, in miles per hour, of the car

45.3 miles per hour

Step-by-step explanation:

1 hour=60 minutes

60/3=20

20*2=40

30 1/5=151/5

(151/5)/40=x/60

cross product

40*x=(151/5)*60

40x=9060/5

40x=1812

x=1812/40

x=45.3

h is the x-coordinate of the vertex

step-by-step explanation:

we have

in this function

the point represent the vertex of the function

so

h is the x-coordinate of the vertex

k is the y-coordinate of the vertex
