Now here there are two cars and for the car a we have been given that the car a travelled west.
00:13
How much we will see.
00:17
So the car a has travelled in the west direction at 9 a .m.
00:24
And the speed was 30 km per hour.
00:30
Now consider the same car.
00:34
A at 12 noon we will have that 3 hours have been passed.
00:44
So at 12 noon that is after complete 3 hours we will have that a has traveled how much 3 into 30? that is it will be 90 kilometers in the west direction.
01:05
Now we have the car b and for car b let t be the time from 12 noon so that both the cars are in the same time frame.
01:23
So from 12 noon the time is denoted by t so clearly at 12 noon the value of t will be 0 and at 2 p .m.
01:37
The value of t will be equal to two hours.
01:46
So now after 12, we will have a has traveled t hours, that is how much distance it has covered? it has covered 30 multiplied by t kilometers.
02:09
And for b has traveled t r's, in t r's it has completed a distance of 45 t kilometer...
