Hi.
The distance between the sun and Earth is given equal to be 14.9 ×10^7 and speed of light is 3×10^8 therefore, by time=distance/speed;
we have
time=(14.9 ×10^7)/3×10^8
which comes out to be an approximate 8 min 20 seconds

speed is equal to distance travelled by time taken. so time will be distance travelled by speed. therefore t = 149000000/300000 sec = 496.66666........... sec = 496.7 sec
