Question

Ravi takes 20 minutes to reach from his house on this cycle if the speed of his cycle is 5 metre per second calculate the distance between his house and market

Answer 1

Answer :

Time of journey = 20 min

Speed of cycle = 5m/s

We have to find distance between house and market$.$

⧪ Speed is defined as the ratio of distance travelled to the time taken.

◕ It is a scalar quantity having only magnitude.

◕ It can't be negative or zero.

◕ Dimension formula : [L¹T‾¹]

◕ SI unit : m/s

First of all, we need to convert unit of time.

★ Conversion (min → s) :

• 1 min = 60 s
• 20 min = 20 × 60 = 1200s

★ Calculation :

⭆ speed = distance / time

⭆ distance = speed × time

⭆ distance = 5 × 1200

⭆ distance = 6000m = 6km

Cheers!

Answer 2

Answer :-

To Find :-

The Distance between Ravi's house and the market.

Given :-

• Time = 20 min

• Speed of Ravi = 5 m/s

Formula Used :-

⠀⠀⠀⠀⠀⠀⠀Speed (In Uniform motion) :-

$\underline{\boxed{\bf{Speed = \dfrac{Distance\:covered}{time\:taken}}}}$

Concept :-

From the Formula for speed of an object , we get the relation for distance as :-

$:\implies \bf{Speed = \dfrac{Distance\:covered}{time\:taken}} \\ \\ \\ :\implies \bf{Speed \times time\:taken = Distance\:covered} \\ \\ \\ \therefore \purple{\bf{Distance\:Covered = Speed \times time\:taken}}$

Hence, the formula for distance covered by an object is :-

$\boxed{\bf{Distance\:covered = Speed \times time\:taken}}$

Now , we can use this Fornula to Find the distance covered between Ravi's house and market.

A/c ,

We know that the SI unit of speed is m/s.

So let's convert the other units in SI unit .

Here , the time taken by the object is 20 min , so to convert it in seconds , we will have to multiply it by 60.

$:\implies \bf{20 min} \\ :\implies \bf{(20 \times 60) s} \\ :\implies \bf{1200 s} \\ \therefore \purple{\bf{20 min = 1200 s}}$

Hence , the time taken by Ravi in Seconds is 1200 s.

Solution :-

Given :-

• Speed = 5 m/s

• Time Taken = 1200 s

Let the distance be x m.

So , by using the Formula for distance of an object and substituting the values in it , we get :-

$:\implies \bf{Distance\:Covered = Speed \times time\:taken} \\ \\ :\implies \bf{x = 5 \times 1200} \\ \\ :\implies \bf{x = 6000} \\ \\ \therefore \purple{\bf{Distance\:Covered = 6000 m}}$

Hence, the distance covered by Ravi is 6000 m.
