If I'm right, then the answer would be B. 800. Hope I helped!
Answer:
two different ways this could be done.
Step-by-step explanation:
There is no graph in your question. If p is number of reams of paper, and c is number of ink cartridges, then
3p + c = 234, wich p and c natural numbers (including 0)
This means that 13 ink cartridges and 0 paper will satisfy the end amount, but also 0 ink cartridges and 39 paper. There are 14 combinations possible.
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
