Write down what you know: distance d = 260 km, time t = 2 hours. You are asked for the speed v.
- 2
Use the formula speed = distance ÷ time:
- 3
Answer with the unit: 130 km/h.
- 4
The same formula rearranged: distance = speed × time (130 × 2 = 260 km) and time = distance ÷ speed (260 ÷ 130 = 2 hours).

\[ v = \frac{d}{t} = \frac{260}{2} = 130\ \text{km/h} \]
\[ v = \frac{d}{t} = \frac{260}{2} = 130 \]How far at 130 km/h
