Answer:
he can subtract the distance and then divide by the time it takes him
Explanation:
Answer:
Average velocity = 30 miles per hour
Explanation:
Given that
Velocity for uphill = 20 miles per hour
Velocity for downhill = 60 miles per hour
We know that
Distance = Velocity x time
Total distance = Average velocity x total time
Lets take distance from home to school is s
Time taken from home to school= s/20 hr
Time taken from school to home= s/60 hr
Total time =s/20+s/60
Total distance = Average velocity x total time
s + s = Average velocity x (s/20+s/60)
So average velocity = 30 miles per hour
An object has positive acceleration if it is accelerating and travelling in the right direction.
<h3>What does it signify if a position time graph has a straight line with a positive slope?</h3>
- A straight line with a positive slope will appear on the Position vs. Time graph of an item travelling forward at a constant speed. It shows that the object's velocity is constant and that it is travelling ahead.
- The y-axis of this sort of graph denotes position in relation to the starting point, while the x-axis denotes time. An object's distance from its beginning position at any given moment since it began moving is displayed on a position-time graph.
- In a distance-time graph, the object's speed is equal to the slope or gradient of the line. The line becomes steeper as the thing goes more quickly (and the greater the gradient).
- The starting point of the item is indicated by the y-intercept. An object's y-intercept is zero if it begins at the measuring instrument. Its y-intercept is 3 meters if it begins at a distance of 3 meters. When two items are in the same position, you may tell by where two lines intersect.
