(67.5-60.5)X = 60+75 X = 18 minutes. Distance from East Village = 67.5x18+75x18 = 2565.

When you understand the problem 1, you will know how to solve problems 2 and 3. There is no need to list two equations. The key is not to directly set the problem as unknown, but to set a key condition for solving the problem as X, so I won't solve it for you here. This is your homework after all.
