# Speed and Time

**Vedic Maths trick to find Speed and Time**

#####
Q1) Suresh walking ^{1}/_{2}^{th} of his usual speed.Find the change in time taken to cover a particular distance .If the usual time to cover the distance is 40 minutes.

**Formula of speed :**

**Usual Time = Numerator * Time**

Putting the value in the farmula:

Let the Time = A minutes

40 = 1 * A

40 / 1 = A

A = minutes let

**Change in time will be mintutes.**

#####
Q2) Suresh walking ^{1}/_{3}^{th} of his usual speed.Find the change in time taken to cover a particular distance .If the usual time to cover the distance is 20 minutes.

**Formula of speed :**

^{Numerator * Time} / _{Difference of Numerator and Denominator} = Usual Time

This formula is used only when difference between numerator and denominator is more then 1.

Putting the value in the farmula:

Let the Time = A minutes

1 * A / 2 = 20

A = 20 * 2 / 1

A = 40 / 1

A = 40 minutes let

**Change in time will be 40 mintutes.**

^{Numerator * Time}/

_{Difference of Numerator and Denominator}= Usual Time
