A rescue mission is being conducted using a plane to drop supplies and medical personnel. A helicopter is also sent from the same base station to rescue wounded persons. If the plane flies 400 mph, the helicopter flies 200 mph, and they leave at the same time, how far away is the rescue site if the helicopter arrives 1 hour after the plane arrives? If t represents the time that the plane flies, which of the following equations could be used to solve the problem?

1. 400/t = 200/(t + 1)
2. 400t = 200(t + 1)
3. 400t = 200t + 1

Colin listed his assets and liabilities on a personal balance sheet. colin’s balance sheet (august 2013) assets liabilities cash $1,500 credit card $500 stocks $800 rent $800 car $5,000 car loan $1,200 coin collection $1,200 student loan $5,000 total total which statement is true about the total assets and the total liabilities? the total of the assets and the liabilities are the same. the total of the assets is greater than the total of the liabilities. the total of the assets is less than the total of the liabilities. the total of the assets cannot be compared to the total of the liabilities.

Me because some of question i don’t understand
