How long will it take the spacecraft to reach Saturn?

Question

A spacecraft leaves Earth's orbit at a speed of 7*10^5 km per day. To travel from Earth to Saturn, the craft needs to travel a total distance of 1.4*10^9 km. How long will it take the spacecraft to reach Saturn?

Answer 1

Distance=speed*tme, so time=distance/speed=1.4*10^9/7*10^5=0.2*10*4=2000 days=2000/365.25=5.5 years approximately.
