Question

Planet Tatoone is about 1.7 AU from its Sun. Approximately how long will it take for light to travel from the Sun to Tatoone in minutes? Use 3 × 108 m/s for the speed of light.

Answer 1

The value is
`t =  14.129 \  minutes`

Step-by-step explanation:

From the question we are told that

The distance of planet Tatoone is
`d =  1.7 \ AU  =  1.7 *1.496* 10^(11)=2.543*10^(11) \ m`

The speed of light is
`c =  3.0*10^(8) \  m/  s`

Generally the time taken is mathematically represented as

`t =  (d)/(c)`

=>
`t =  (2.543*10^(11))/(3.0*10^(8) )`

=>
`t =  847.7 \  s`

Now converting to minutes

`t =  (847.7)/(60)`

=>
`t =  14.129 \  minutes`
