Shortcut Methods and Tricks for Numerical:

• 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 Trick: For quick distance calculation in km, multiply the speed in km/h by the time in hours.

• Numerical 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.

• Numerical 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 Trick: For quick distance calculation in km, multiply the speed in km/h by the time in hours.
