Heat is a form of electromagnetic radiation.

Explanation:

It therefore travels with the speed of light, which is almost $300000$ km/s
As the average distance from the sun is about $150$ million km, this will take:
$\frac{1500 \cancel{00000}}{3 \cancel{00000}} = 500 s = 8 m 20 s$

Infra red waves a form of electro magnetic radiation brings heat to earth from Sun.

Explanation:

They travel at speed of light and takes about 8 minutes and 20 seconds to reach earths surface.
