WebWhen solving these problems, use the relationship rate (speed or velocity) times time equals distance. r⋅t = d r ⋅ t = d For example, suppose a person were to travel 30 km/h for 4 h. To find the total distance, multiply rate times time or (30km/h) (4h) = 120 km. The problems to be solved here will have a few more steps than described above. WebThe unknown in this problem is the rate or percentage. Since the statement is " (thirty) is (some percentage) of (twenty)", then the variable stands for the percentage, and the equation is: 30 = ( x ) (20) 30 ÷ 20 = x = 1.5. Since x stands for a percentage, I need to remember to convert this decimal back into a percentage: 1.5 = 150%.
