A car travels 440 km in 4 hours. What is its average speed?

The average speed is 110 km/h.

v = \frac{d}{t} = \frac{440}{4} = 110\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 440 km, time t = 4 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{440}{4} = 110$
3
Answer with the unit: 110 km/h.
4
The same formula rearranged: distance = speed × time (110 × 4 = 440 km) and time = distance ÷ speed (440 ÷ 110 = 4 hours).
