A car travels 370 km in 4 hours. What is its average speed?

The average speed is 92.5 km/h.

v = \frac{d}{t} = \frac{370}{4} = 92.5\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 370 km, time t = 4 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{370}{4} = \frac{185}{2} = 92.5$
3
Answer with the unit: 92.5 km/h.
4
The same formula rearranged: distance = speed × time (92.5 × 4 = 370 km) and time = distance ÷ speed (370 ÷ 92.5 = 4 hours).
