Question

8. A man walking at a speed of 10 km/hr takes 12 minutes to complete one round of the park.
Find the distance covered by him.​

Answer 1

Answer:

• He covered 2 km of distance.

Step-by-step explanation:

Given that:

• A man walking at a speed of 10 km/hr.
• Time taken to complete one round of park is 12 minutes.

To Find:

• The distance covered by him.

First converting the time in hours:

We know that.

⇒ 1 minute = 1/60 hours

⇒ 12 minutes = 12/60 hours

⇒ 12 minutes = 0.2 hours

Finding the distance covered by him:

Formula: Distance = Speed × Time

⟶ Distance = 10 × 0.2

⟶ Distance = 2

∴ The distance covered by him = 2 km

Answer 2

Given : A man walking at a speed of 10 km/hr takes 12 minutes to complete one round of the park .

Need To Find : The Distance Covered by man .

⠀⠀⠀⠀⠀━━━━━━━━━━━━━━━━━━━⠀

⠀⠀⠀⠀As , We can see that the speed is given in km/h so and time is given in minutes so First we need to Convert the time from minutes to hours .

⠀⠀⠀⠀Converting the time from minutes to hours :

As , We know that ,

$\qquad \:\bigg\lgroup \sf{ 1 \:hrs \: = 60 min }\bigg\rgroup$

Therefore ,

$\qquad \:\bigg\lgroup \sf{ 1 \:min \: = \dfrac{1}{60} hrs }\bigg\rgroup$

Now ,

$\qquad \longmapsto \sf 12 min = \cancel {\dfrac{12}{60}} hrs$

$\qquad \longmapsto \sf 12 min = 0.2 hrs$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm {\:Time \:taken \:is\:\bf{0.2\:hrs}}}}$

⠀⠀⠀⠀Finding Distance Travelled by man :

$\dag\:\:\it{ As,\:We\:know\:that\::}$

$\qquad \dag\:\:\bigg\lgroup \sf{ Distance \:: Speed\times Time }\bigg\rgroup$

⠀⠀⠀⠀Here the given speed is 10 km/hr & the Time taken is 0.2 hrs .

⠀⠀⠀⠀⠀⠀$\underline {\boldsymbol{\star\:Now \: By \: Substituting \: the \: known \: Values \::}}$

$\qquad \longmapsto \sf Distance = 10 \times 0.2$

$\qquad \longmapsto \frak{\underline{\purple{\:Distance = 2 km }} }\bigstar$

Therefore,

⠀⠀⠀⠀⠀$\therefore {\underline{ \mathrm {\:Distance \:Travelled \:by\:man\:is\:\bf{2\:km}}}}$
