An airplane on autopilot took 5 hours to travel 3 comma 510 kilometers. what is the unit rate for kilometers per hour?
i need

702 kilometers per hour.

Step-by-step explanation:

3,510 divided by 5 = 702.

Since 5 is the number of hours it took to travel 3,510 kilometers, and we need to find the kilometers per hour, simply divide 3,510 by 5.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.

the correct is answer is a 9-sided polygon!
