A car travels 360 miles in 1 hour. What is its average speed?

The average speed is 360 mph.

v = \frac{d}{t} = \frac{360}{1} = 360\ \text{mph}

How to work it out

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