After 1 hour the slower car will be 30 mph x 1 hour = 30 miles ahead of the faster car. The faster car is travelling 45 mph - 30 mph = 15 mph faster than the slower car and so will cover this 30 miles in 30 miles ÷ 15 mph = 2 hours at which point it will have caught the slower car and start to over take it.
Start out early.
After 3,000 miles you should have your oil changed and I believe after the first 1,000 miles on a new car it should be changed. If you have a lot of miles on your vehicle it might start burning oil.
The distance between the start point and the destination is 148 miles, and will take approximately 2 hours 21 minutes of driving time.
After several miles, your car will start missing, better to go ahead a drain it.
The more miles driven and the older the car, the less in value the car will be. If you are at the point where you are having to make major repairs on the car then it is time to sell.
