When forming a ratio, it is important to remember that you MUST have the same units. So, in this problem, convert the hours to minutes:

3 hours = 3*60 = 180 minutes.

Now, compare Marc's minutes to Angelina's minutes, and write it as a fraction:
180/150

Reduce the fraction by dividing numerator and denominator by 30:
6/5

R^2
