Final answer:
To convert kilometers per hour to miles per hour, divide the speed in km/h by 1.609. If you are traveling at 65 mph and need to drive 125 kilometers to El Paso, it will take approximately 1 hour and 55 minutes.
Step-by-step explanation:
To convert kilometers per hour to miles per hour, we can use the conversion factor of 1 mile = 1.609 kilometers. So, if the speed limit is 100 km/h, we can calculate the equivalent speed in miles per hour as follows: 100 km/h * (1 mile / 1.609 km) = 62.14 mph. Therefore, a speed limit of 100 km/h is approximately 62.14 mph.
In the given question, if you are traveling at 65 mph and need to drive 125 kilometers to El Paso, you can calculate the time it will take by using the formula time = distance / speed. Therefore, the time it will take is 125 km / 65 mph = 1.92 hours (or approximately 1 hour and 55 minutes).
