It would take about 4.8 years to travel from earth to Saturn.
<h3>How long would it take?</h3>
We know that speed is expressed as the ratio of distance to time. In this case, we are trying to know ow many years would it take to reach the planet Saturn travelling at 21 thousand miles per hour.
Given that;
Speed = 21 thousand miles per hour
time taken = ???
Distance = 887 million miles
Speed = distance/time
speed * time = distance
time = distance/speed
time = 8.87 * 10^8 miles/2.1 * 10^4 miles per hour
time = 4.22 * 10^4 hours
If 8.766 * 10^3 hours make 1 year
4.22 * 10^4 hours make 4.22 * 10^4 hours * 1 year/8.766 * 10^3
= 4.8 years

Basis For Comparison CFL Bulb LED Bulb
Definition The CFL is defined as the lamp which uses the low pressure mercury vapour gas for producing the visible light It is a PN junction diode which produces light when current passes through it in the forward direction.
Stand For Compact Fluorescent Lamp Light Emitting Diode
Working principle The electrons of mercury when excited emits ultraviolet light. This ultraviolet light when strikes with the fluorescent coating glass converts it into the visible light. The semiconductor material which emits light with the passage of current.
