Time, Speed and Distance


Time is the ongoing sequence of events taking place. The past, present and future. We measure time using seconds, minutes, hours, days, weeks, months and years.


How fast something is moving. Measured as distance traveled per unit of time.

Example: The speed of these cars is over 150 kilometers per hour (150 km/h).


Distance is the space between two objects or points.

Relationship between Time, Speed and Distance is:

Speed = Distance/Time


A person crosses a 600 m long street in 5 minutes. What is his speed in km per hour?



An aeroplane covers a certain distance at a speed of 240 kmph in 5 hours. To cover the same distance in 1\(2\over3\) hours, it must travel at a speed of:


Excluding stoppages, the speed of a bus is 54 kmph and including stoppages, it is 45 kmph. For how many minutes does the bus stop per hour?


In a flight of 600 km, an aircraft was slowed down due to bad weather. Its average speed for the trip was reduced by 200 km/hr and the time of flight increased by 30 minutes. The duration of the flight is:


The ratio between the speeds of two trains is 7 : 8. If the second train runs 400 km in 4 hours, then the speed of the first train is:
