How do you calculate time saved by speeding?
Going from 40 mph to 50 mph will save 19 minutes, but going from 80 mph to 90 mph will only save 5 minutes: Same 10 mph increase, but pretty big differences in time saved. More formally, an increase in speed of X% means a 11+X100 decrease.
How much time does 10 mph save?
One researcher actually created a breakdown of the difference speeding makes: 15–mile trip, 55 mph speed limit, 10 miles over the speed limit: 2.51 minutes saved. 30–mile trip, 55 mph speed limit, 10 miles over the speed limit: 5.04 minutes saved.
How many lives do speed limits save?
This study measures these changes and obtains surprising results. We find that the 65 mph limit reduced statewide fatality rates by 3.4% to 5.1%, holding constant the effects of long-term trend, driving exposure, seat belt laws, and economic factors.
Is driving fast worth it?
‘Going really fast is not worth it’: Study shows speed-related fatalities increase as speed limits do. A pickup truck with four teenage passengers and a 21-year-old driver. Traveling more than 85 mph on a curvy road with a posted speed limit of 55 mph.
How do you calculate speed when driving?
How do you calculate mph to seconds?
- Take your current speed in either kmph or mph.
- Divide it by 60 to get kilometers per minute or miles per minute.
- Divide by 60 again, getting kilometres per second or miles per second.
- Alternatively, divide it by 3600 for the straight conversion.
What is the most important passing rule?

How much time does speeding save in school zones?
Reducing the speed to 40 kilometres/hour, as in school zones, reduces the likelihood of death by a factor of 4 compared with 60 kilometres/hour, and of course the likelihood of an impact is also dramatically reduced Hard to argue with that. One of my greatest worries is a selection bias that happens with this type of argument.
