Question

*The time in which a train covers a distance 3600 km at a speed of 60 km/hr. What will be the distance covered in same time at speed of 80 km/hr?*

1️⃣ 60 km
2️⃣ 48 km
3️⃣ 4800 km
4️⃣ 6000 km​

Answer 1

Answer:

⠀⠀⠀⠀⠀⠀⠀⠀⠀According to the Question

• Distance covered in by train ,d₁ = 3600 km
• Speed of train ,s₁ = 60km/hr

Firstly we calculate the time taken by train in first case ,

Let the time taken in 1st case be t₁

As we know that Speed is defined as the distance covered by body in per unit time.

• s = d/t

Substitute the value we get

$:\implies$ s₁ = d₁/t₁

$:\implies$ 60 = 3600/t₁

$:\implies$ t₁ = 3600/60

$:\implies$ t₁ = 60 hour

• So,the time taken in 1st case is 60 hours

It is given in 2nd case that the time taken is same as first was .

Let the distance covered by train in 2nd case be d₂

Now. distance covered by train in 2nd case is

$:\implies$ d₂ = s₂× t₂

$:\implies$ d₂ = 80 × 60

$:\implies$ d₂ = 4800 km

• Hence, the distance covered by train in 2nd case is 4800 km .

So the required option is (3) 4800 km .

Answer 2

$\large\bf\underline\red{Question \: :- }$

★ The time in which a train covers a distance 3600 km at a speed of 60 km/hr. What will be the distance covered in same time at speed of 80 km/hr?

$\large\bf\underline\red{Answer \: :- }$

Given :-

• A train travels 3600km at speed 60km/hr.

To find :-

• What is distance at speed 80km/hr.

Solution :-

We know that,

$★ \: {\small{\underline{\boxed{\bf{\pink{Speed = \frac{Distance }{ Time} }}}}}}$

Putting the values by given question

$⇢\sf{80 = \frac{distance}{60} }$

$⇢\sf{distance = 80 \times 60}$

$\sf\pink{⇢Distance = 4800km}$

4800km covered in same time at speed of 80 km/hr.

Answer : (3) 4800km
