You are stuck in a big traffic jam on the freeway and wondering how long it will take to get to the next exit, which is 1 1/2 miles away. You are timing your progress and find that you can travel 2/3 of a mile in one hour. If you continue to make progress at this rate, how long will it take you to reach the exit? Solve this problem with a diagram and explain your answer. Ok so I am confused on what to do and need some help. :)

you can divide. It'n not exactly following the directions, but much quicker than a diagram would be.

You need the amount of time it takes to travel l $1\frac{ 1 }{ 2 }$ miles at $\frac{ 2 }{ 3 }$ miles per hour.

time = distance / rate
$$1\frac{ 1 }{ 2 }\div \frac{ 2 }{ 3 }$$

^do you know how to do that?

I think I do do you have to find the common denominator to divide?

anonymous · Answer

no you don't need a common denominator. 
I'd convert 1 1/2 to an improper fraction, change the division sign to multiplication, and flip 2/3 to 3/2
