A car travels a distance of 540km in 6hrs. What speed did it travel at?

If you would like to know the speed of the car, you can calculate this using the following steps:

540 km ... 6 hours

x km = ? ... 1 hour

540 * 1 = 6 * x

540 = 6 * x

x = 540 / 6

x = 90 km

The correct result would be 90 km per hour.
