Divide 65 (miles per hour you are traveling) by 60 (minutes in an hour) to find out how many miles a minute you are going. you get approximately 1.083 miles per minute. Divide the amount of miles (125) by the miles you are traveling per minute (1.083). the answer is 115 minutes.
Theoretically, it should be possible to travel 125 miles at 65 mph in 115 minutes. But it's not possible to give a real-life answer to the question, since nobody has ever been able to drive all the way from San Diego to Malibu and maintain 65 mph.
