I just can't figure out how to set this problem up. Is it a quadratic equation? Please help. (Headbang)

Gail drives 10 miles per hour slower than Dexter. With two more hours of driving time, Gail travels a total of 330 miles, compared to Dexter who travels 260 miles. Find the speed and time traveled for each.

I would appreciate any help. Thank you so much. (Nod)
