While riding trax at a constant speed of 16 m/s you walk toward the front of the car at 5 m/s. what is your velocity relative to someone standing outside the train?: )

Speed of the TRAX is given as 16 m/s so let say it is given as

now our speed towards the front end is given by 5 m/s so this is the relative speed of us with respect to TRAX

let say this speed is given as

now we need to find the speed with respect to someone standing outside the TRAX

so here we need to find the net speed in ground frame and hence we can use the formula of relative speed

so someone outside the TRAX will see our speed as 21 m/s

the answer would most likely be c, because if it's a comical piece of information, it may likely not be true, if it's a site that allows anybody to edit the content, it could mean a five year old is typing the info, and if it's a tv show produced by a celeb, it may have a biased opinion.
