Person a leaves home to visit his cousin, person b, who lives 140 miles away. he travels at an average of 52 mph. one half-hour later, person b leaves her house to visit person a, traveling at an average rate of 62 mph. how long after person b leaves her house will it be before they meet?

(D)

Step-by-step explanation:

The quadratic equation is in the form :

and In the above, (p + q) = b and pq = c.

To factor a quadratic, we'll need to start by finding the two numbers (being the p and the q above) that add up to equal b, where those numbers also multiply to equal c.

Since, both 3 and 5 in the given equation are prime numbers, thus the given equation cannot be factorised because of the prime nature.

Hence, option D is correct.
