A car travels 260 km in 8 hours. What is its average speed?

The average speed is 32.5 km/h.

v = \frac{d}{t} = \frac{260}{8} = 32.5\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 260 km, time t = 8 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{260}{8} = \frac{65}{2} = 32.5$
3
Answer with the unit: 32.5 km/h.
4
The same formula rearranged: distance = speed × time (32.5 × 8 = 260 km) and time = distance ÷ speed (260 ÷ 32.5 = 8 hours).
