Question

a car travels 30 km in 20 minutes then find out speed of the car​

Answer 1

Answer:-

• Distance travelled by the car=30km
• Time taken=20min=1/3hour

We know that

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

$\\ \qquad\sf\longmapsto Speed=\dfrac{30}{\dfrac{1}{3}}$

$\\ \qquad\sf\longmapsto Speed=\dfrac{30\times 3}{1}$

$\\ \qquad\sf\longmapsto Speed=90km/h$

$\\ \underline{\boxed{\bf{\therefore Speed\:of\:the\:car=90km/h}}}$
