A car travels 360 km in 10 hours. What is its average speed?

The average speed is 36 km/h.

v = \frac{d}{t} = \frac{360}{10} = 36\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 360 km, time t = 10 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{360}{10} = 36$
3
Answer with the unit: 36 km/h.
4
The same formula rearranged: distance = speed × time (36 × 10 = 360 km) and time = distance ÷ speed (360 ÷ 36 = 10 hours).
