Kit moved 60 feet closer to the ticket window in 30 minutes.
This means she moved at a rate of $\frac{60 \text{ ft}}{30 \text{ min}} = 2 \text{ ft/min}$.
There are 3 feet in a yard, so 70 yards is equal to $70 \times 3 = 210$ feet.
At a rate of 2 ft/min, it will take Kit $\frac{210 \text{ ft}}{2 \text{ ft/min}} = \boxed{105}$ minutes to move the remaining 70 yards to the ticket window.
The answer is: 105
