The correct answer is: [A]: " 29.4 ft. "
___________________________________________________
Explanation:
___________________________________________________
Solve for "b" ; which is the "base" .
14.7 ft. = (1/2) * b ;
→ (1/2) * b = 14.7 ft ;
Multiply EACH SIDE of the equation by "2" ;
to isolate "b" on one side of the equation; & to solve for "b" ;
___________________________________________________2 * { (1/2) b } = 2 * (14.7 ft) ;
to get:
b = 29.4 ft . ;

→ which is: Answer choice: [A]: " 29.4 ft. "

Answer:
Step-by-step explanation:
Givens
<em>Student A</em>
d = 3/4 mile
t = 6 minutes
<em>Student B</em>
d = 1/2 mile
t = 5 minutes
Note
In both cases, the units are the same, so unit conversion is not necessary.
Solution
<em>Student A</em>
r = d / t
r is the rate of travel in miles / minute
r = 3/4 / 6
r = 3.4 // 6/1 The 1 is put below the 6 so it is easier to divide. Invert the bottom and multiply.
r = 3/4 * 1/6
r = 3/24
r = 1/8 miles / minute
<em>Student B</em>
r = d / t
r = 1/2 // 5 / 1 Turn the bottom fraction upside down and multiply
r = 1/2 * 1/5
r = 1/10
Question
which is bigger: 1/8 or 1/10?
1/8 = 0.125
1/10 = 0.1
1/8 is bigger by 0.025
Answer
Student A is faster by 0.025 miles / minute.
