I having mind meld about how to figure out the ratio cause if u go an average of seven miles per hour over the speed limit and there is ten different speed limit changes and one hundred twenty miles between cities. I would like a formula and explaination of the process. I was thinking for every ten miles u would lose 7 minutes in ur travel time so it would be around eighty four minutes travel time versus one hundred twenty minutes. Help please!

Why do you think you would lose time? Suppose you start at at speed limit of 35 mph. You are traveling then at 42 mph. After a while, the speed limit changes to 40 mph so you are now traveling at 47 mph. Next speed limit becomes 45 mph, so you are now traveling at 52 mph. Continue the process by increasing your speed limit by 5 mph each time until you have encountered 10 speed limit changes.
So at all times you are traveling 7 mph above the speed limit.
So you should get there faster than if you always obeyed the speed limit -- not slower.
Even if the speed limit should go frdown fro say 75mph to 65 mph, you are still traveling faster than the legal limit. So where is this 7 minute loss per 10 minutes? It does not compute.
