Choice B is correct. It’s given that Rhett drove at an average speed of miles per hour and that he drove for hours. Multiplying miles per hour by hours yields miles, or the distance that Rhett drove. It’s also given that Jessica drove at an average speed of miles per hour and that she drove for hours. Multiplying miles per hour by hours yields miles, or the distance that Jessica drove. The total distance, in miles, that Rhett and Jessica drove can be represented by the expression . It’s given that the total distance they drove was under miles. Therefore, the inequality represents this situation.
