- [0](https://md.mova.elamur.ai/free/en/corpora/school/lessons/112-speed/0/) — Speed tells how far something goes in one hour: a car going 60 km each hour has a speed of 60 km an hour.
- [1](https://md.mova.elamur.ai/free/en/corpora/school/lessons/112-speed/1/) — Distance = speed × hours: in 3 hours that car goes 60 × 3 = 180 km.
- [2](https://md.mova.elamur.ai/free/en/corpora/school/lessons/112-speed/2/) — If you know the distance for some hours, divide to get the speed: 120 km in 2 hours is 120 / 2 = 60 km each hour.
- [3](https://md.mova.elamur.ai/free/en/corpora/school/lessons/112-speed/3/) — Going the other way, hours = distance / speed: 240 km at 60 km an hour takes 240 / 60 = 4 hours.
