Question #5
|
| Yes, it was this very car racing around the track. |
A car is doing some practice laps around a track. A person with a stopwatch clocks the driver going around the track exactly 12 times in 10 minutes and 25.3 ± 0.2 seconds. Each lap is 2800 ± 5 m in length.
If the driver wanted to know their speed in kilometres per hour, the speed's absolute uncertainty is closest to...
- 0.1 s
- 1.3 km/h
- 0.4 km/h
- 0.1 km/h
