If an airplane moves at a constant speed of 120 miles per hour for 3 hours. How far does it go?

360 miles

Step-by-step explanation:

For every one hour traveled, 120 miles are covered. If there are three hours traveled, then we would have 120+120+120 (aka 120*3). At the end of the 3 hours, we will have traveled 360 miles. Thank you for choosing Southwest, enjoy your day.

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.
