Question

3. Aston and Damian live in cities D and A respectively. D is on a higher elevation than A.
Due to this, whenever someone drives from D towards A, their driving speed becomes
10% more than their speed on plain ground. Also, whenever someone drives from A
towards D, their driving speed becomes 10% less than their speed on plain ground. Aston
and Damian simultaneously start driving from their respective cities towards the other
city. When they reach the other city, they immediately turn back and return to their own
cities. When they reach their own cities, they immediately turn back towards the other
city and meet exactly at the midpoint between the two cities. What is the ratio of the
speeds of Aston and Damian on plain ground?
1.9:11
B.49:51
C.39:41
D.29:31
