Comparing an electric car to a petrol car by “tank versus charge” doesn’t really work – the containers are different sizes and the fuel is priced completely differently. The fair comparison is cost pe…
As the crow flies vs driving distance explained: why roads add about 30 percent, plus how to measure the straight-line distance on Google Maps.
Driving time is distance divided by your average speed, not the speed limit. How to estimate realistically with traffic, stops, and rest breaks, with examples.
Driving cost barely changes with more passengers; flying scales per person. How to compare the true cost of a road trip and flights, with break-even factors.
The driving habits that genuinely cut fuel use: easing off speed, smooth acceleration, correct tyre pressure, and less weight and drag, ranked by impact.
Two ways to split a restaurant bill: evenly, or by what each person ordered. How to share tax and tip fairly, with a worked example and rounding tips.
How to calculate travel time: divide distance by average speed. 300 km at 75 km/h takes 4 hours. Learn to convert decimal hours and add a real-world buffer.
How to calculate average speed: divide total distance by total time. 150 km in 2 hours is 75 km/h. Learn why you cannot just average two speeds.
