A car travels 470 km in 1 hour. What is its average speed?

The average speed is 470 km/h.

v = \frac{d}{t} = \frac{470}{1} = 470\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 470 km, time t = 1 hour. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{470}{1} = 470$
3
Answer with the unit: 470 km/h.
4
The same formula rearranged: distance = speed × time (470 × 1 = 470 km) and time = distance ÷ speed (470 ÷ 470 = 1 hour).
