Earths average speed?

Question

EK I dont get this my teacher explained it to one person in the class and no one else. HELP!!!!!!!!

Every year the Earth travels about 10^9 km as it orbits the Sun. What is Earth's average speed in km/h

Answer 1

You have the speed in km per year. So divide by the number of days in a year to get the average speed in km per day, and then by the number of hours in a day to get the average speed in km per hour.
