Shortcut Methods
JEE Exam
- Numerical Trick:
When calculating speed in km/h, remember 1 km/h = 5/18 m/s. Use this conversion to easily convert km/h to m/s for distance calculations.
- Numerical 2 Trick:
For quick distance calculation in km, multiply the speed in km/h by the time in hours.
- Numerical 3 Trick:
To calculate the distance travelled in minutes, directly multiply the speed in m/s by the time in minutes. No need to convert minutes to seconds.
CBSE Board Exam
- Numerical Trick:
Follow the same speed conversion trick as in JEE Numerical 1.
- Numerical 2 Trick:
For distance calculation in km, you can directly multiply the speed in km/h by the time in minutes. However, remember to divide by 60 to convert minutes to hours.
- Numerical 3 Trick:
For quick distance calculation in km, multiply the speed in km/h by the time in hours.
