Neptune orbits the sun in about 1.45×10⁶ hours at a speed of about 1.95×10⁴ km per hour approximately what distance in km does Neptune travel in one orbit

Question

anonymous

A 2.83×10⁹ km
B 2.83×10¹⁰ km
C 2.83× 10²³km
D 2.83×10²⁴km

Answer 1

To find the distance Neptune travels in one orbit, we can multiply the speed by the time it takes to complete one orbit.

Distance = Speed x Time

Distance = (1.95×10⁴ km/h) x (1.45×10⁶ hours)

Using some basic multiplication rules for scientific notation, we can simplify the calculation:

1.95 x 1.45 = 2.8275

10⁴ x 10⁶ = 10¹⁰

So the distance Neptune travels in one orbit is approximately 2.83×10¹⁰ km.

Therefore, the correct answer is B) 2.83×10¹⁰ km.
