Step-by-step explanation:
At time 2:00 PM 
A car reads = 30 mi/h
At time 2:20 PM
A car reads = 50 mi/h
Now,
At time 2:00 PM 
t = 0
At time 2:20 PM
t =

Answer:
B
Step-by-step explanation:
Given
(4x + 3)(3x - 4)
Each term in the second factor is multiplied by each term in the first factor, that is
4x(3x - 4) + 3(3x - 4) ← distribute both parenthesis
= 12x² - 16x + 9x - 12 ← collect like terms
= 12x² - 7x - 12
The coefficient of the x- term is - 7 → B
 
        
             
        
        
        
Train A: Speed of 60 mph. (1 mile per minute)
Train B: Speed of 90 mph. (1.5 miles per minute)
after 2 hours: (2:00)
Train A has gone 120 miles. (half-way mark)
Train B has gone 0 miles.
Hour 2:48: (2:48) 
Train A has gone 168 miles.
Train B has gone 72 miles.
72 ----><---------------168
At 2:48 P.M the two will meet. 72+168=240
I hope this helps! :)
