Yes they will be equal at some point. Although Marc has more miles on his car at the current moment, Elena is adding miles at a higher rate.
Elena's car: 7000 + 21000t
Marc's car: 20000 + 11000t
To find at what time t they are equal, set these two expressions equal to each other and solve for t.
7000 + 21000t = 20000 + 11000t
13000 = 10000t
t = 1.3 years from now
