1) You've been given a speed, and a distance, and you must find a time. So first, identify the formula that relates the three, which is: speed x time = distance

2) Taking the unknown time as x (in hours, since the speed is given in hours), plug the values into the formula
=> 55x = 440

3) The problem says that she would like to complete AT LEAST 440 miles, which means she could also cover a greater distance. Thus, the left side of the equation could also be greater than 440.
=> 55x >= 440

4) Now you can divide by 55 on both sides to obtain the inequality for x.
