This question here describes a driving situation where we have a car behind a truck.
00:11
So let's write down the information that we have.
00:15
For the car, we know that the velocity of the car is 88 kilometers per hour.
00:30
And the initial position of the car is, i'm going to say, negative because they are behind the truck and they are 110 meters behind okay i need to convert that into kilometers because my distance unit here is kilometers so my conversion factor is one kilometer is equal to 1 ,000 meters okay so i'm gonna i'm put it down below.
01:06
The car is negative .11 kilometers behind the truck.
01:15
Okay.
01:16
So if we were to represent the motion of the car with an equation, the position of the car is equal to the car's velocity times time plus the initial position.
01:30
Okay.
01:31
So the position of the car is going to be 88t minus 0 .11.
01:40
Okay.
01:41
Now i want to do the same thing for the truck.
01:47
Okay.
01:48
The truck has a velocity of 75 kilometers per hour...
