From 8:25 am to 30 seconds past 8:29 am, there are 4.5 minutes. Her speed is calculated by dividing the distance of the post office from her house by the time.

         Speed = 0.75 mile / 4.5 minutes = 1/6 mile / minute

Determining the number of minutes she will have to take in order to reach school,

         Time = 3.42 mile / (1/6 mile/minute) = 20.52 minutes

Adding this to the initial time,

           Final time = 8:25 am + 20.52 minutes

                    = 8:45 am and 31.2 seconds.

She will reach the school on time even without increasing her speed.

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.
