The car catches up with the truck after a distance of 360 miles from point A.
Speed is the ratio of distance travelled to total time taken. It is given by:
Speed = distance / time
For truck:
60 = d / t
d = 60t
Since the car leaves the truck after 2 hours, hence:
For the car:
90 = d/ (t - 2)
d = 90t - 180
For the truck and car to catch up:
60t = 90t - 180
30t = 180
t = 6 hours
d = 60t = 60(6) = 360 miles
The car catches up with the truck after a distance of 360 miles from point A.

The trinomial function; x²+6x+10 when written in the form (x+a)²+b is; (x + 3)² + 1.
<h3>What is a trinomial function?</h3>
In a bid to write the trinomial function; x²+6x+10 when written in the form (x+a)²+b;
We must first divide the coefficient of x in the trinomial by 2 so that we have; 6/2 = 3.
In essence, a = 3; so that we have;
However, the trinomial given is; x²+6x+10.
Therefore;
- x²+6x+10 = (x² + 6x + 9) + 1
- x² + 6x + 10 = (x + 3)² + 1.
