If the speed limit is 50 mph and you drive 10 mph over, how many minutes would you save on a 10-mile trip?

To understand how much time is saved during a 10-mile trip when driving over the speed limit, we can look closely at the calculations involved.

If you are driving at the speed limit of 50 mph, you can calculate the time taken to cover 10 miles by using the formula: time = distance / speed. In this case, time = 10 miles / 50 mph, which equals 0.2 hours, or 12 minutes.

Now, if you drive 10 mph over the speed limit, your new speed would be 60 mph. Using the same formula, the time taken for the trip at this higher speed would be: time = 10 miles / 60 mph, which equals approximately 0.167 hours, or about 10 minutes.

To find the time saved by increasing your speed, you subtract the time taken at the higher speed from the time at the speed limit: 12 minutes - 10 minutes equals 2 minutes.

Thus, by driving 10 mph over the speed limit on a 10-mile journey, you save 2 minutes of travel time. This is how we arrive at the answer.
