Question 1002958
You want to convert this to:
[ miles that you travel ] / [ 1 hour ]
This is your rate of speed
----------------------------
Your fraction is:
{{{ 20 / ((3/4)) }}}
Multiply the top and bottom by {{{ 4/3 }}}
{{{ 20*(4/3) / 1 }}}
{{{ 80/3 = 26.667 }}} mi/hr
-----------------------
The goal was to get [ miles traveled ] / [ 1 hr ]
which is what you read on the speedometer
of a car
------------
Does this help, or did I miss what's confusing you?
