Question

A car is travelling with uniform speed while covering a distance of 24 km in 20 min. Calculate the speed with which the distance was covered.

Answer 1

Explanation:

20 metre per second conversion of units are very important. I think this answer is correct though I have a little confusion due to that uniform speed in the question.

Answer 2

$\large\underline{\bigstar \: \: {\sf Given-}}$

• Distance covered by car (s) = 24km in time (t) = 20min

$\large\underline{\bigstar \: \: {\sf To \: Find-}}$

• Speed with which the Distance was covered (v).

$\large\underline{\bigstar \: \: {\sf Formula \: Used -}}$

$\implies\underline{\boxed{\sf Speed=\dfrac{Distance}{Time}}}$

$\large\underline{\bigstar \: \: {\sf Solution-}}$

✪ Convert minute into second

$\implies{\sf t=20\;min}$

$\implies{\sf t=20\times 60}$

$\implies{\bf t=1200\:s}$

✪ Convert km into metre

$\implies{\sf s=24\: km}$

$\implies{\sf s=24 \times 1000}$

$\implies{\bf s = 24000\;m }$

____________________________________

$\implies{\sf v=\dfrac{s}{t} }$

$\implies{\sf v=\dfrac{24000}{1200 }}$

$\implies{\bf v = 20\: m/s}$

$\large\underline{\bigstar \: \: {\sf Answer-}}$

Speed of car is ${\bf 20\: m/s}$
