In the given question we are told that there are two planes that are leaving chicago at the same time and they are flying in the opposite directions.
00:10
So, let's say at this point is where chicago is and one plane is traveling at a speed of 450 miles per hour and the other plane is traveling in the opposite direction in the speed of 550 miles per hour.
00:34
And now what we are told to find is how long will it take for them to be 4000 miles apart.
00:46
So, what we could do over here is we can write let's say this is plane number one and this the other one is plane number two.
01:01
So, the speed at which the speed let's write the parameters for plane two, the speed is 550 miles per hour.
01:20
The time that it would take for the train to cover a distance, let's say the time that we take, we are taking the time same for two planes because we have to find the time that it would take for them to be 4000 miles apart, right.
01:43
So, let's say the time that we take over here is t hours and the distance covered in t hours would be the speed multiplied by the time taken.
01:59
So, 550 times t miles would be covered in t hours.
02:07
Similarly, if you take the case of plane one, it is going at a speed of 450 miles per hour...
