can you please show me the steps for this word problem? in need to write the inequality and solve. how long will Kenzie drive if she averages 55mph and wants to complete at least 440 mi. of her trip?

Answer 1

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.

Answer 2

please let me knoe if this is correct 55/55 + > 440/5 t=8. is it written correctly please show me if not thats where my problem comes

Answer 3
