What is it?

To find out "what is slower than" something means to compare speeds and identify which object or person takes more time to cover the same distance, or covers less distance in the same amount of time. The object that takes longer or covers less distance is considered slower.

Simple Example

Quick Example

Imagine two friends, Rohan and Priya, are cycling to the school gate. Rohan takes 5 minutes, and Priya takes 7 minutes. Since Priya takes more time to reach the same gate, Priya is slower than Rohan.

Worked Example

Step-by-Step

Let's compare the speeds of three auto-rickshaws travelling from the market to the railway station, which is 10 km away.

Step 1: Auto A takes 20 minutes to cover 10 km.
---Step 2: Auto B takes 25 minutes to cover 10 km.
---Step 3: Auto C takes 18 minutes to cover 10 km.
---Step 4: To find out which auto is slower, we look for the one that takes the longest time to cover the same distance.
---Step 5: Comparing the times: Auto A (20 min), Auto B (25 min), Auto C (18 min).
---Step 6: The longest time is 25 minutes, taken by Auto B.
---Answer: Auto B is slower than Auto A and Auto C.

Why It Matters

Understanding 'slower than' helps us compare rates and make smart choices, from choosing the fastest delivery service to designing efficient machines. In fields like logistics and transportation, knowing relative speeds is crucial for planning routes and schedules, and even in AI, algorithms compare data processing speeds.

Common Mistakes

MISTAKE: Thinking 'slower' means a smaller number for time. | CORRECTION: For the same distance, 'slower' means taking a *larger* amount of time. More time = slower.

MISTAKE: Comparing objects that travel different distances in different times. | CORRECTION: To accurately compare 'slower than', make sure either the *distance* is the same or the *time* is the same for all objects being compared.

MISTAKE: Confusing 'slower' with 'less powerful'. | CORRECTION: 'Slower' specifically refers to speed or rate of movement/progress, not necessarily strength or power. A powerful truck might be slower than a small car in a race.

Practice Questions

Try It Yourself

QUESTION: A tortoise walks 1 meter in 2 minutes. A snail walks 1 meter in 5 minutes. Which animal is slower? | ANSWER: The snail is slower.

QUESTION: Train P travels 100 km in 2 hours. Train Q travels 100 km in 3 hours. Which train is slower? | ANSWER: Train Q is slower.

QUESTION: Reena can type 50 words in 1 minute. Sameer can type 80 words in 2 minutes. Who is slower at typing? (Hint: Find out how many words each types in 1 minute). | ANSWER: Sameer is slower. (Reena types 50 words/min, Sameer types 40 words/min)

MCQ

Quick Quiz

Which of these statements correctly describes 'slower than'?

It covers more distance in less time.

It covers less distance in the same amount of time.

It covers the same distance in less time.

It always means the object is bigger.

The Correct Answer Is:

Option B is correct because if something is slower, it will cover less distance than a faster object in the same amount of time. Options A and C describe something faster, and D is incorrect as size doesn't determine speed.

Real World Connection

In the Real World

When you order food online from apps like Swiggy or Zomato, the app calculates the estimated delivery time. If one restaurant shows 30 minutes and another shows 45 minutes for the same dish, the one taking 45 minutes is 'slower' in terms of delivery speed. This helps you choose the faster option.

Key Terms

SPEED: How fast something moves or happens. | TIME: The duration taken for an event. | DISTANCE: The amount of space between two points. | COMPARE: To look at two or more things to see how they are similar or different.
