Answer:

Temperature in Fahrenheit will be 124.52°F and in kelvin 324.4 K

We have to convert this temperature in Fahrenheit and kelvin

For Fahrenheit

Temperature in Fahrenheit = $\frac{9}{5}\times 51.4+32=124.52^{\circ}F$

For kelvin

In kelvin = 51.4+273 = 324.4 K

So temperature in Fahrenheit will be 124.52°F and in kelvin 324.4 K
