The speed of light is around 6.706×10^8 miles per hour. What is the speed of light in units of miles per minute?
Sindrei [870]

<u>Answer:</u> The speed of light in miles per minutes is 1.117\times 10^7miles/min

<u>Explanation:</u>

We are given the speed of light is 6.706\times 10^8miles/hr and we need to convert it into miles/min. So, we use the converion factor:

1 hour = 60 minutes

Converting that quantity into miles/minutes, we get:

(\frac{6.706miles}{1hr})(\frac{1hr}{60min})=\frac{1.117\times 10^7miles}{min}

Hence, the speed of light in miles per minutes is 1.117\times 10^7miles/min
