What is it?

Faster means completing a task or covering a distance in less time. When we compare two things, the one that finishes first or takes less duration is considered faster.

Simple Example

Quick Example

Imagine two friends, Rohan and Priya, are both eating a plate of delicious biryani. Rohan finishes his biryani in 5 minutes, while Priya takes 8 minutes. Since Rohan took less time to finish the same amount of biryani, Rohan ate faster.

Worked Example

Step-by-Step

Let's compare two delivery scooters, Scooter A and Scooter B, going from a shop to a customer's house, which is 10 km away. --- Scooter A completes the 10 km distance in 20 minutes. --- Scooter B completes the same 10 km distance in 15 minutes. --- To find out which is faster, we compare the time taken. --- Scooter A took 20 minutes. --- Scooter B took 15 minutes. --- Since 15 minutes is less than 20 minutes, Scooter B took less time. --- Therefore, Scooter B is faster than Scooter A.

Why It Matters

Understanding 'faster' helps us choose the most efficient way to do things, whether it's for travel, computing, or even sports. Engineers use this concept to design faster trains and internet. In AI, it helps develop algorithms that process information quicker, making apps and smart devices more responsive.

Common Mistakes

MISTAKE: Thinking 'faster' means covering more distance. | CORRECTION: 'Faster' is about taking LESS time for the SAME distance, or covering MORE distance in the SAME time. Time is the key factor.

MISTAKE: Confusing speed with being faster. | CORRECTION: Speed is a measure (distance/time), while 'faster' is a comparison. Something that is faster has a higher speed.

MISTAKE: Not considering the task or distance. | CORRECTION: Always compare 'faster' in relation to the same task or the same distance covered. You can't compare who is faster if they are doing different things.

Practice Questions

Try It Yourself

QUESTION: A bus travels from Delhi to Agra in 3 hours. A car travels the same distance in 2 hours. Which vehicle is faster? | ANSWER: The car is faster.

QUESTION: Two students, Anil and Bharat, are solving a math problem. Anil solves it in 1 minute 30 seconds. Bharat solves it in 95 seconds. Who is faster? | ANSWER: Anil is faster (1 minute 30 seconds = 90 seconds, which is less than 95 seconds).

QUESTION: A mobile phone downloads a 100 MB game in 40 seconds. Another mobile phone downloads a 120 MB game in 45 seconds. Which phone has a faster download speed per MB? | ANSWER: Phone 1: 100MB / 40s = 2.5 MB/s. Phone 2: 120MB / 45s = 2.67 MB/s (approx). So, the second phone has a faster download speed per MB.

MCQ

Quick Quiz

Which of these situations describes something being faster?

A train covers 500 km in 8 hours.

A bicycle covers 10 km in 30 minutes.

A person runs 100 meters in 15 seconds, while another person runs 100 meters in 12 seconds.

A chef prepares biryani in 1 hour.

The Correct Answer Is:

Option C directly compares two things doing the same task (running 100 meters) and shows one taking less time (12 seconds vs 15 seconds), which means it is faster. Other options just state a single event.

Real World Connection

In the Real World

When you book a cab or auto-rickshaw using an app like Ola or Uber, the app often shows you the estimated time of arrival. If there are two routes, the app will suggest the 'faster' route, which is the one that takes less time to reach your destination, helping you save time.

Key Vocabulary

Key Terms

TIME: The duration in which something happens. | DISTANCE: The length between two points. | SPEED: How fast an object is moving (distance covered per unit time). | COMPARISON: Looking at two or more things to see how they are similar or different.
