So here in this question, it is given that you and your friend was at an intersection and your friend drives away north with a constant speed.
00:10
And we are staying or the first person is staying at the intersection for an hour.
00:16
And after an hour that the friend departs from the intersection, he leaves to the east with the speed 11 miles per hour faster than the friend's speed.
00:27
So i'm just drawing all the activities over here.
00:32
So this was the intersection and the front is more towards north.
00:37
It was given.
00:39
So let's draw it like this.
00:42
This will be towards north.
00:44
So towards north let the speed be x miles per hour.
00:51
So this was the speed of the front and after one hour.
00:56
So after one hour you are departing.
00:59
Towards east this will be the direction that towards east and the speed will be 11 miles per hour faster than your friend speed so this speed will be x plus 11 miles per hour so that will be the speed so the question it was given or the next date it is given is two hours after your friend's departure which means the time is now two hours after the friend's departure that means you will be traveling for one hour and friend will be traveling for two because this person was started after one hour of the friend's departure.
01:43
So the you will be traveling for one hour and the friend will be traveling for two hour.
01:50
And it is given that the distance between the two of you after two hours of the friend's departure is 106 miles and we are asked to find the speed of the front...
