Does Speeding Actually Save Time?
See how much time speeding actually saves on different journey lengths
| Distance | At 100 km/h | At 120 km/h | At 140 km/h | Time Saved (120→140) |
|---|---|---|---|---|
| 50 km | 30min | 25min | 21min | 3min |
| 100 km | 60min | 50min | 42min | 7min |
| 200 km | 120min | 100min | 85min | 14min |
| 300 km | 180min | 150min | 128min | 21min |
| 500 km | 300min | 250min | 214min | 35min |
Note: Higher speeds significantly increase fuel consumption and accident risk

Frequently Asked Questions
Common questions about car speed and travel calculations
How do you calculate car travel time?
To calculate car travel time, divide the distance by your average speed. Formula: Time = Distance / Speed. For example, a 200 km journey at 80 km/h takes 200 / 80 = 2.5 hours (2 hours 30 minutes).
How much fuel does a car use per 100 km?
Average fuel consumption varies by vehicle type: small cars use 5-7 L/100km, medium cars 7-9 L/100km, large cars 9-12 L/100km, and SUVs 10-15 L/100km. Highway driving is typically more efficient than city driving.
How much time does speeding actually save?
Speeding saves less time than most people think. On a 100 km journey, driving at 130 km/h instead of 100 km/h saves only about 14 minutes. The time savings decrease on shorter trips and don't account for increased fuel consumption and accident risk.
What is a safe following distance at highway speeds?
The recommended safe following distance is at least 2 seconds in ideal conditions, increasing to 4+ seconds in rain or poor visibility. At 100 km/h, a 2-second gap equals about 56 meters.
