I've just started physics and I'm having difficulty with this problem.I'd really appreciate some help with how to go about doing it!Thanks!

'The speed of light is 299800000 m/s. How many times could a light beam

travel around the Earth in one day (the radius of the Earth is 6370 km)'

Do I need to get the circumference of the earth first?
