4.Time, Speed and Distance Flashcards
What is the formula to calculate speed?
Speed = Distance/Time
What is the formula to calculate time?
Time = Distance/Speed
What is the formula to calculate distance?
Distance = Speed * Time
What is the formula for average speed?
Average Speed = Total Distance/Total Time
What is the relation between speed, time, and distance in a constant speed scenario?
Speed = Distance/Time or Time = Distance/Speed or Distance = Speed * Time
How do you convert speed from km/h to m/s?
Divide the speed in km/h by 3.6 to get the speed in m/s.
How do you convert speed from m/s to km/h?
Multiply the speed in m/s by 3.6 to get the speed in km/h.
What is the formula for relative speed when two objects are moving in the same direction?
Relative Speed = Speed of Object A - Speed of Object B
What is the formula for relative speed when two objects are moving in opposite directions?
Relative Speed = Speed of Object A + Speed of Object B
How can you calculate the time taken to cover a given distance with different speeds?
Time = (Distance/Speed1) + (Distance/Speed2) + (Distance/Speed3) + …
How can you calculate the distance covered in a given time with different speeds?
Distance = (Speed1 * Time) + (Speed2 * Time) + (Speed3 * Time) + …
What is the formula to calculate the time taken to cover a round trip?
Time = 2 * (Distance/Speed)
What is the formula to calculate the average speed for a round trip with different speeds?
Average Speed = (2 * Speed1 * Speed2) / (Speed1 + Speed2)
How can you calculate the time difference between two locations in different time zones?
Time Difference = (Longitudinal Difference/15) * 1 hour
In boat problems, what is the formula to calculate the speed of a boat in still water?
Boat Speed = (Speed of Downstream + Speed of Upstream) / 2
