A car travels 370 miles in 2 hours. What is its average speed?

The average speed is 185 mph.

v = \frac{d}{t} = \frac{370}{2} = 185\ \text{mph}

How to work it out

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