A car travels 410 km in 11 hours. What is its average speed?

The average speed is 37.272727 km/h.

v = \frac{d}{t} = \frac{410}{11} = 37.272727\ \text{km/h}

How to work it out

1
Write down what you know: distance d = 410 km, time t = 11 hours. You are asked for the speed v.
2
Use the formula speed = distance ÷ time:
$v = \frac{d}{t} = \frac{410}{11} = \frac{410}{11} = 37.272727$
3
Answer with the unit: 37.272727 km/h.
4
The same formula rearranged: distance = speed × time (37.272727 × 11 = 410 km) and time = distance ÷ speed (410 ÷ 37.272727 = 11 hours).
