I want to know an easy and less time consuming way to solve equations especially equations based on distance, time and speed.

There are no such easy ways to solve equations based on distance, time and speed.

 

Infact, there is no such way to solve any problem of any subject.

 

Please be thorough with the concepts of Time, Distance and Speed and understand the relations between them.

 

Also, be thorough with the change of units from kilometer to meter and hour to minutes and minutes to seconds.

 

All the best!!!!
