Answer:

8 minutes and 20 seconds

Step-by-step explanation:

Average Distance between Earth and Sun: 150 million km =
1.5 * 10^(8) km

Velocity of light:
$3 * 10^(8) \ m/s = 3 * 10^(5) \ km/s$

Time = Distance/Speed

or Time =
$1.5 * 10^(8) \ km$ /
$3 * 10^(5) \ km/s$

= 5 * 100

= 500 seconds

⇒ Time = 8 minutes and 20 seconds
