Easiest Shortcut Trick for Time and Distance Problems in Mathematics

Hello Readers, finally the wait is over. Today, we are publishing the Shortcut trick for solving Questions based on Time and Distance.
Video Tutorial is coming Soon!!!

Type-1(Fraction Based)
Q1, Running 3/4 of his usual speed, a person is 12 minutes late to his office. What is the usual time to cover the distance?
                    (a) 48 min                       (b) 50 min
                    (c) 36 min                       (d) 38 min

Sol with trick :  Have a look on fraction i.e 3/4. Here the lower value i.e numerator 3 represents the usual time whereas higher value i.e denominator 4 represents the increased time. We have to find usual time so we will focus on 3.

The answer is 36 Minutes

Q2. A train meets with an accident and moves at 5/7 of its usual speed. Due to this, it is 14 minute late. What is the original time of the journey beyond the point of accidents.
                    (a) 32 min                     (b) 35 min
                    (c) 40 min                     (d) 45 min
Sol  - Again we have to find the original speed so we will focus on numerator because it's value is smaller than denominator value.

The answer is 35 minutes

Q3. A person covered certain distance with 7/11 of his usual speed in 22 hours. How much time he saved to reach the same distance with his usual speed?
                    (a)8 hours               (b) 16 hours
                    (c) 15 hours            (d) 10 hours
sol - Here we have to find the time saved so we will solve this question in below given manner.

Type -2 ( Percentage Based Questions)
Q1. A person covers certain distance with 20% more than his original speed and reach 8 minutes earlier. What is the original time of the journey?
               (a) 46 min                     (b) 32 min
               (c) 45 min                     (d) 48 min

Sol -

Type -3 (Reaches Early late)
Before i give the trick, please note down below given points . 
  • If Late and Early is mentioned in the question, Addition will be perfomed
  • If Late and Late is mentioned , Subtraction will be performed.
  • If Early and Early is mentioned, Subtraction will be performed. 
Q1. A ma convers certain distance from his house to office at 30 km/h and late by 10 minutes. However, with a speed of 40 km/h, he reaches his office 5 minutes earlier. What is the distance?
                    (a) 20 km                           (b) 30 km
                    (c) 40 km                            (d) 50 km
