Answer 2

Step-by-step explanation:

$x = \sqrt{t + 3}$

we know speed is dx/dt

so differentiate it

by chain rule .

$\frac{dx}{dt} = \frac{d( \sqrt{t + 3}) }{(d(t + 3))} \times \frac{d(t + 3)}{dt}$

$= \frac{1}{2 \sqrt{t + 3 } } \times t$

at t = 1 sec

$= \frac{1}{2 \sqrt{4} }$

$= \frac{1}{4} = 0.25m \: per \: second$
