velocity of light is 6.71 * 10^8 miles per hour.
mercury is approximately 5.78 * 10^7 kilometers from the sun.
how many minutes for the light to get from the sun to mercury?

1 kilometer = 0.621371192 miles

divide both sides of this equation by .621371192 and you get:

1 mile = 1.609344001 kilometers

this means that 5.78 * 10^7 kilometers equals 9.302008324 * 10^7 miles.

1 minute = 1 hour / 60

this means that 6.71 * 10^8 miles per hour equals .111833333333 * 10^8 miles per minute.

Rate * Time = Distance

This translates to:

Time = Distance / Rate

Our distance is 9.302008324 * 10^7 miles

Our rate is .111833333333 * 10^8 miles per minute.

We divide (9.302008324 * 10^7) by (.111833333333 * 10^8) to get:

minutes.

Answer is:

It takes 8.317742167 minutes for light to reach mercury from the sun.

Somehow the distance the other tutor calculated for Mercury to the sun is the distance from the earth to the sun.
9.3*10^7 miles is the distance from the earth to the sun
Using your calculations in miles which is close to the average 36 million miles.
3.5915254911*10^7/(6.71 × 10^8*60)=3.21 minutes not 8 minutes which it takes to the earth
