Answer:
(A) Question 1
Step-by-step explanation:
First, we count how far reached the Nell:
3,5 * 16 = 56 miles
Secondly, we count how far reached the Kristin:
3,5 * 18 = 63 miles
Now we expect the difference in the distance between them:
63 - 56 = 7 miles
The results that Kristin about seven miles driven more than Nell.
Option B: (b-a)/(b+a) is the correct answer
Step-by-step explanation:
The given expression is;

First of all we have to take LCM in both numerator and denominator
So,

The reciprocal of the denominator will be multiplied with the numerator for simplification
So,

Hence,
Option B: (b-a)/(b+a) is the correct answer
