How many minutes would it take for sunlight to travel from the sun to the Earth?

The approximate distance from the Earth to the Sun is 93 million miles. If the speed of light is about 3.00 x 10^8 m/s, how many minutes would it take for sunlight to travel from the sun to the Earth?



Please show me how to do this, it would be a great help.How many minutes would it take for sunlight to travel from the sun to the Earth?Remember that speed = distance/time.

From this: time = distance/speed



This is a very easy problem, you should at least try to do it by yourself.How many minutes would it take for sunlight to travel from the sun to the Earth?
Eight (8) minutes.How many minutes would it take for sunlight to travel from the sun to the Earth?Find out meters in a mile, multiply that by 93 million, divided by 3.00 x10^8 would give you miles per second, then you have to divide by 60, for minutes,



It takes about 8 minutes and 19 seconds.How many minutes would it take for sunlight to travel from the sun to the Earth?
convert 93 million miles to meters

convert 3.00E8 m/s to m/min by multiplying by 60 sec/min

then divide distance in meters by speed of light in meters/minHow many minutes would it take for sunlight to travel from the sun to the Earth?speed = distance / time



time = distance / speed



google calculator

93 million miles = 149 668 992 000 meters



time = 149 668 992 000 m / 3 x 10^8 m/s



time = 498.9 s





time = 498.9 / 60 minutes



time = 8.315 minutesHow many minutes would it take for sunlight to travel from the sun to the Earth?
Not evan a minut it takes 8 sec for light to get to the erath from th sun
8.3 minutes.



1 metre / second = 0.000621371192 miles / second.

3.00 x 10^8 m/s = 186,400miles/second.



(93,000,000 miles / 186,400 miles/second) / 60sec/min = 8.3minutes.
