A car travels 460 km in 11 hours. What is its average speed?

The average speed is 41.818182 km/h.

v = \frac{d}{t} = \frac{460}{11} = 41.818182\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 460 km, time t = 11 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{460}{11} = \frac{460}{11} = 41.818182$
3
Answer with the unit: 41.818182 km/h.
4
The same formula rearranged: distance = speed × time (41.818182 × 11 = 460 km) and time = distance ÷ speed (460 ÷ 41.818182 = 11 hours).
