distance from sun to earth: 93,000,000 miles
speed of light: 300,000,000 meters per second
1.6 kilometers=1 mile
1 kilometer=1000 meters
1 hour = 3600 seconds
i did this problen twice and i got two different answers: roughly 0.14 hours or 7.25 hours
alot of other people did it too but we all got different answers

Your .14 answer is correct, because sunlight takes about 8 minutes to get here.
.14hrs * (60minutes/ 1 hour) = 8.4 minutes

Distance to the sun in km:
93,000,000 * 1.6 = 148,800,000 km
Distance to the sun in meters:
148,800,000 * 1,000 = 148,800,000,000 meters
At 300,000,000 meters/sec, number of seconds needed to get to the sun:
148,800,000,000 / 300,000,000 = 496 seconds
In minutes, that's 496 / 60 = 8.267 minutes (8 minutes 16 seconds)
In hours, that's 8.267 / 60 = 0.1377 hours.

93,000,000 miles= 148,800,000 kilometers
300,000,000 meters per sec=300,000 kilometers per sec
the time= 148,800,000 / 300.000= 496 seconds
496 seconds= 8,26 minutes

Using your data, the distance is:
9.3 * 10^7 miles
= 9.3 * 1.6 * 10^7 km
= 9.3 * 1.6 * 10^10 m
The time taken is:
= 9.3 * 1.6 * 10^10 / (3 * 10^8) sec.
= 9.3 * 1.6 * 10^10 / ( 3 * 3.6 * 10^11 ) hr.
= 0.14hr.

300,000,000 m = 300,000 km
93,000,000mi x 1.6km/1mi x 1sec/300,000km x 1min/60sec = 8.2min.
