Would you multiply 125 and 65?

Answer 11

Sorry. I had to leave. The picket fence method is the method whereby you change the dimensions. For instance, in this problem, you are asked how many "minutes" it takes to drive to San Diego but you are given the speed and distance in miles per "hour" and miles. You know that you are traveling 65 miles per hour and that you are driving 125 miles. You can calculate how long it takes because the speed times the time driving will equal the total distance.\[Total miles = speed Xtime\]\[125=65t\]\[t=\left( 125 miles\over 65 miles/hour\right)=t(hours)\]But you want the time in minutes not hours, so to convert the hours to minutes you can multiply the expression by the number of minutes per hour. \[t=\left( 125 miles\over 65 miles/hour\right)\left( 60minutes \over 1 hour \right)=t(minutes)\]
