The distance between the two stations is 216 km. A bus takes 4 hours to cover that distance. Calculate the average speed of the word in km/hour?

Given: The distance between two stations is 216 km and a bus takes 4 hours to cover the distance.

To find: We have to find the average speed of the bus.

Solution: We know that

$Average\ speed\ =\ \frac{Total\ distance}{Total\ time}$

=> $Average\ speed\ =\ \frac{216}{4} \ =\ 54\ km/h$

Hence the average speed  of the bus is 54km/h.
