hope this will help you

Answer 2

Answer:

$\huge\pink{Hello}$

Step-by-step explanation:

$\large\blue{Solution:-}$

$x = 4 {t}^{2} + 7$

Given,

$t = 3$

So,

After differentiation,

x = 8t

So,

$</em></strong><strong><em>S</em></strong><strong><em>peed</em></strong><strong><em> = </em></strong><strong><em>7</em></strong><strong><em> \</em></strong><strong><em>times</em></strong><strong><em> </em></strong><strong><em>3</em></strong><strong><em> </em></strong><strong><em>= </em></strong><strong><em>24m</em></strong><strong><em>$

Hence,

Speed = 24m/s
