Given below are a few subheads under the Speed, Time and Distance topics that tell us the basis of the variety of questions asked in the examination. 1. Average Speed Average Speed = (Total distance traveled)/(Total time taken) Case 1 –When the distance is constant:Average speed = 2xy...
On any path, it goes to some mirror and comes back, and all times must be equal. Here the light always travels in air, so the time and the distance are proportional. Therefore the statement that all the times are the same is the same as the statement that the total distance is the ...
Expect to break any speed or distance(距离) records in a short time. Maybe in the beginning you can only make it halfway across the pool before you need to take a break, and that's okay. As you practice more, you'll be able to swim for longer each time.___ A. It takes time...

Mathematically, if an object travels at a constant speed𝑣such that it moves a distance𝑑in a time𝑡,then speed𝑣is given by𝑣=𝑑𝑡. We can use a speed–time graph to plot an object’s speed at different times. We may recall that the horizontal axis of a graph is called ...
