Hint: Of course, the Earth's spin isn't the only acceleration we have in space. According to Cornell, our orbital speed around the sun is nearly 67,000mph(107,000km/h) . With fundamental geometry, we can measure it.

Complete answer:
In order to calculate the problem, we have to find out how far the Earth goes, first of all. It takes Earth nearly 365 days to orbit the sun. The orbit is an ellipse, so let's assume it's a circle, to make the math easier. So, the diameter of a globe is the Earth's orbit. According to the International Astronomers' Union, the distance from Earth to the sun, considered an astronomical unit, is 92,955,807miles(149,597,870kilometers)
What we consider as radius(r). A diameter equal to 2×π×r is the circumference of the loop. Calculating this, 2×3.14×92,955,807=583,762,467.96. So the Earth flies some 584 million miles in one year (approximately) (i.e.940 million km).
Since speed = distancetime we can also calculate the speed of the Earth by dividing the distance by 365.25 days. And dividing the outcome by 24 hours in order to get miles per hour or kilometers per hour.

Note: Since the Earth's orbit around the sun is elliptical, it is very much like a circle. It is possible to model the orbit by x2+y2=8649,here the sun is at its origin, and each coordinate plane is 1 million miles in length. The orbital speed of Earth is 29.78km/s (107,208km/hr;66,616mph) on average, which is rapid enough to reach the diameter of the planet in 7 minutes and the distance to the Moon in 4 hours. Earth will seem to revolve in a counterclockwise fashion around the Sun from a perspective near the north pole of either the Sun or Earth.
