Shortcut Tips & Formulas to Solve Time, Speed & Distance Problems Faster
- Km/hr to m/sec Conversion
- m/sec to km/hr Conversion
- If the ratio of the speeds of X and Y is x : y, then the ratio of the the time taken by them to cover the same distance is:
1/x : 1/y or y : x
- If a train covers a certain distance x km/hr and an equal distance at y km/hr. Then,
GMAT Quant Problem Solving Tips:
- Analyze the given statements in the problem independently. Whether the information given in each statement is sufficient for you to arrive at the solution of the question. You can combine both the statements to help you solve the problem.
