Good day.
00:02
The topic is about constant speed motion.
00:05
At constant speed, we define the ratio of distance and time as a constant.
00:18
Where we have it as v equals t over t, where v is the speed, t is distance, and t is the time.
00:28
Now consider a scenario where tourist, that is d meters away, from a car is being followed by a bear that's originally or that is 26 meters away from the tourist.
00:52
So this is a tourist and this is where we say a is for the tourist and b is for the bear.
01:01
Now in this case, of course the tourist as if got scared will frantically run towards the car.
01:10
And we are looking now for the distance d so that the tourist can reach the car and get safe and be safe from the bear.
01:28
That is also pursuing it.
01:29
Now the tourist is moving towards the car at the speed of 4 meters per second and that the bear is moving at 6 meters per second.
01:41
So the bear moves faster.
01:43
But with this d distance we will solve later we know that the tourists will still be safe...
