Bob goes to run. From his starting point, he runs due east at 10 ft per sec for 250 ft. He then turns and runs north at 12 ft per sec for 400 ft. He then turns and runs west at 9 ft per sec for 90 ft.
Express the (straight-line) distance from Bob to his starting point as a function of t, the number of seconds since he started.
This was the graph , or sketch I MADE about this problem, so if you have an easier idea, feel free to post, since it says he keeps turning to the direction in which he turn in
So the first part was d=s(t) from his starting point (Point A) to his second point (Point B), so we know that the speed there was 10 ft/s so then d=10t
Now I have to find the others
I know that the equation we would be using is the distance formula, but since time is included, this is making it difficult for me. Can anyone help explain to me what do you do on this problem?
