Driving 100 miles
On a highway at a steady 60 mph, 100 miles takes 1 h 40 min — at that speed each mile takes exactly one minute. At 70 mph it’s 1 h 26 min, and at 30 mph through town it’s 3 h 20 min.
Real trips are slower than these numbers. Traffic lights, junctions, congestion and roadworks lower your average speed, so an urban route usually takes much longer than the limit suggests. To estimate your own average, divide distance by the time a similar trip took — or use the average speed calculator.
