MHB What is the Average Speed of a Train Traveling 18 km in 20 Minutes?

[mathlearn]

The total distance traveled by trains is 18 km & the time spent is 20 minutes. Find the average speed of the train in kilometers per hour.

I' m stuck right in the beginning in converting 20 minutes to hours by dividing from 60 which I get this recurring decimal 0.33333

You don't need a decimal value...

$$\overline{v}=\frac{d}{t}=\frac{18\text{ km}}{\dfrac{1}{3}\text{ hr}}=54\text{ kph}$$

Thanks :D The times when you got to decide between fractions and decimals
