__General Knowledge:__It is good to bear in mind the following equations: Average Distance = Average Speed * Average Time Average Speed = Average Distance / Average Speed Average Speed = Average Distance / Average Time

__The Problem:__A bus travels at an average speed of 32kph. It travels a distance of 56km from Liverpool to Manchester. How long does the journey take? Use the formula: Time = Distance / Speed Hence: 56/32 = 1.75 = 1 hour and (0.75 * 60) 45 minutes
