Question

. A car taken 10 min to cover 10 km of distance. What is its speed in km/hr ?​

Answer 1

Answer:

60 km/hr

Explanation:

Distance = 10 km

Time = 10min = 10/60 hrs

Speed = ?

Speed = distance / time

Speed = 10/1/6 km/hr

Speed = 60 km/hr

Answer 2

Answer:

Given:

Distance covered = 10 km

Time taken = 10 minutes.

To find:

Speed of car in km/hr

Concept:

Speed is defined as the instantaneous rate of change of position (distance) with respect to time.

Speed is an scalar Quantity , having only magnitude and no Direction. By speed , we usually mean tge average speed in a whole journey.

Conversion:

Since the question asks to measure speed in km/hr , we need to convert the unit of time from minutes to kilometers.

$\bigstar \: \: \sf{10 \: min = \dfrac{10}{60} = \dfrac{1}{6} \: hr}$

Calculation:

$\bigstar \: \: \sf{speed = \dfrac{distance}{time} }$

$\implies \: \: \sf{speed = \dfrac{10 \: km}{ \frac{1}{6} \: hr } }$

$\sf{ \implies \: \: speed = 60 \: km {hr}^{ - 1} }$

So final answer :

$\boxed{ \red{ \huge{ \bold{ \sf{ speed = 60 \: km {hr}^{ - 1} }}}}}$
