Mike walked for 40 minutes with the speed of 3 mph. How far did he walk?

2 miles

Step-by-step explanation:

40 min = 40:60 = 2/3 hours.

Distance: 3 mph * 2/3 h = 2 miles

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.
