A.![d=\sqrt{(190-7t)^2+(130-4t)^2}](/tpl/images/0714/5453/457a3.png)
B. Minimum distance between them = 18.61 feet.
C. After 28.76 seconds Sven and Rudyard are closest.
Step-by-step explanation:
A) Let (0,0) be the intersection point.
Then, Initial Location of Sven (0,190).
Speed of Sven = 7 feet per second
Then, position of Sven after t seconds = (0,190-7t) [speed = distance x time]
Similarly, Initial position of Rudyard= (130,0)
Speed of Rudyard = 4 feet per second
Position after t seconds = (130-4t,0)
Distance d between Sven and Rudyard t seconds after they start walking:
B) Let![d(t)=\sqrt{(190-7t)^2+(130-4t)^2}\\](/tpl/images/0714/5453/3d5e9.png)
Put d'(t)=0
Minimum distance :
Hence, the minimum distance between them = 18.61 feet.
c) After 28.76 seconds Sven and Rudyard are closest.
