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

150/60=2.5 HOURS 3:2.5 NOW MULTIPLY BOTH TERMS BY 2 &YOU GET 3*2:2.5*2=6:5
