Since Aaron left the city at 12pm (noon) and needs to be arrive at the next city at 3pm he has exactly 3 hours. Since he is going 65 km/h we need to divide 185 by 65 to find out how long it will take for Aaron to travel 185km.
186 / 65 = 2.86
Aaron will arive at the next city in 2.86 hours meaning he will not arrive late and will arive on time. I hope this helps you :D
