A man travels at a speed of 18 kmph. Find the distance covered by him in 72 seconds.

Here are some handy tips for solving time and distance questions in quantitative aptitude: The basic formula for time, speed, and distance (TSD) is: Distance: Distance = Speed x Time Average speed: Average speed = Total Distance / Total Time Relative speed: When objects are moving in the same direction, subtract the slower object's speed from the faster one Average speed when a person covers a distance at one speed and returns at another speed: Average speed = 2ab / (a + b), where 'a' and 'b' represent the two speeds involved  Other useful time/distance formulas include: Speed =...

Here are some handy tips for solving time and distance questions in quantitative aptitude:

The basic formula for time, speed, and distance (TSD) is: Distance: Distance = Speed x Time
Average speed: Average speed = Total Distance / Total Time
Relative speed: When objects are moving in the same direction, subtract the slower object's speed from the faster one
Average speed when a person covers a distance at one speed and returns at another speed: Average speed = 2ab / (a + b), where 'a' and 'b' represent the two speeds involved 

Other useful time/distance formulas include:
Speed = Distance/Time
Time = Distance/Speed
1 km/hr = 5/18 m/sec
1 m/sec = 18/5 km/hr
