Answer:
8 miles
Explanation:
Velocity is speed+direction (the speed of something in a given direction). We know that running on a track, one is moving forwards, which is why the velocity given as positive. Now we do some simple algebra. 120 minutes is equal to 2 hours. At a velocity of 4 miles an hour, for 2 hours, you multiply 4x2 and get 8, which is how far (in miles, units are important) the man has traveled once he comes to a stop.
Answer:
Although the graph was missing, I managed to find it on another source. According to the given conditions, correct answer is <u><em>option C</em></u><u>. A dog stop at his home for 5 seconds</u>.
Reason:
In the graph, The dog was west of his home then he came back, he stopped at his home then runs to other direction (East).
When the dog was running from west to home, his running speed or velocity was 1 m/s which was then decreased to 0 m/s after reaching home. Here (at home) the dog stopped for a while (5 seconds according to the graph), and his velocity was 0 m/s. Then, he started running again to other East direction with velocity -2 m/s (opposite direction).
