QuestionA video is made of a train traveling 20 feet per second. If the video is played in reverse, describe the location of the train after 4 seconds.
Studdy Solution
STEP 1
1. The train travels at a constant speed of 20 feet per second.
2. The video is played in reverse.
3. We need to determine the location of the train after 4 seconds when the video is played in reverse.
STEP 2
1. Determine the distance traveled by the train in the forward direction.
2. Calculate the distance traveled in reverse.
3. Describe the location of the train after 4 seconds in reverse.
STEP 3
Determine the distance traveled by the train in the forward direction.
The train travels at a speed of 20 feet per second. In 4 seconds, the distance traveled forward is:
STEP 4
Calculate the distance traveled in reverse.
Since the video is played in reverse, the train will appear to move backwards the same distance it traveled forward in 4 seconds, which is 80 feet.
STEP 5
Describe the location of the train after 4 seconds in reverse.
If the train was at a certain location when the video started, after 4 seconds in reverse, it will be 80 feet behind that starting location.
