Two cars left the same place moving in opposite directions, the first car at 65mph and the second 2.5mph faster. When will they
1 answer:
<u>Answer:</u>
Approximately after 2 hours the distance between the two cars will be 268 miles.
Solution:
We know .
Here it is given that the speed of Car 1 is 65 mph and the speed of car 2 is 2.5 mph faster than car 1. It means that the speed of car 2 is (65+2.5) = 67.5 mph
We will use the below given equation to find out the time after which the distance between the two cars will be 268 miles.
Let ‘t’ be the time after which the distance between the two car will be 268 miles.
∴ A/Q,
Therefore, approximately after 2 hour the distance between the two cars will be 268 miles.

We are given with a quadratic equation which represents a Parabola , we need to find the vertex of the parabola , But let's recall that , For any quadratic equation of the form ax² + bx + c = 0 , the vertex of the parabola is given by ;
Where , D = b² - 4ac (Discriminant)
Now , On comparing the given equation with ax² + bx + c , we have
⇢⇢⇢ <em><u>a = 1 , b = - 10 , c = 2</u></em><em><u>7</u></em>
Now , Calculating D ;
Now , Calculating the vertex ;
Hence , The vertex of the parabola is at (5,2)
Note :- As the Discriminant < 0 . So , the equation will have imaginary roots .
