CAT / Time Distance Speed
Click any card to reveal the answer.
In Example 1, if someone travels at 30 km/hr one way and 120 km/hr back, with total time of 5 hours, how do you determine the time spent on each leg?
In Example 2, if traveling at 3/4 of original speed makes a train 10 minutes late, how do you calculate the usual travel time?
What is the key difference between the harmonic mean and arithmetic mean formulas for average speed in special cases?
Why is average speed considered a scalar quantity rather than a vector quantity?
What is the formula for average speed when traveling for equal durations at two different speeds, and why does this formula work?
In the constant distance case derivation, why does total time equal (d/x + d/y) and total distance equal 2d?
What is the general formula for calculating average speed?
How does the relationship between speed and time change when distance is held constant?
What is the definition of average speed and what type of quantity is it?
In the special case where the same distance is covered at two different speeds, what type of mean is used to calculate average speed and why?
