I'm guessing you mean magazines as in bullets. Well, if he paid $412 dollars for two, and each were sold as a multiple of 43. Then each bullet was $4.79.
You find this by dividing 412 by 2 which gives you $206.
Now divide that by 43. Which is $4.79 (.ea) bullet.
Answer:
4.002 x 10^3
Step-by-step explanation:
Let the time = x
Distance = Speed x time
One train is 75x, the other train 85x
Add together to equal total distance:
75x + 85x = 384
Simplify:
160x = 384
Divide both sides by 160:
x = 384 / 160
x = 2.4 hours
