A physicist working in a large laboratory has found that light particles traveling in a particle accelerator increase velocity i
frutty [35]

Answer:

17\ \text{hours and}\ 15\text{ minutes}

Step-by-step explanation:

The function is

-4x+3y=21

Where

x = Time in hours

y = Velocity in kilometers per hour

Here y = 30 km/hr

-4x+3y=21\\\Rightarrow x=\dfrac{3y-21}{4}\\\Rightarrow x=\dfrac{3\times 30-21}{4}\\\Rightarrow x=\dfrac{69}{4}\\\Rightarrow x=17.25\ \text{hours}=17\ \text{hours and}\ 15\text{ minutes}

The particle will reach 30 km/hr after 17\ \text{hours and}\ 15\text{ minutes}.
