Vincent took 1 1/2 times as long as Marcus to finish a school project. If it took them 30 days in total, how much longer did it take Vincent to complete his work?

Let x = time it takes Marcus, then
1.5x = time it takes Vincent.
The total is 30 days; therefore,
x + 1.5x = 30.
Solve for x = M
1.5 x = V.
