A car travels 190 km in 2 hours. What is its average speed?

The average speed is 95 km/h.

v = \frac{d}{t} = \frac{190}{2} = 95\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 190 km, time t = 2 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{190}{2} = 95$
3
Answer with the unit: 95 km/h.
4
The same formula rearranged: distance = speed × time (95 × 2 = 190 km) and time = distance ÷ speed (190 ÷ 95 = 2 hours).
