Question 1057333
.
The distance to your aunt's house is 644 miles, and the distance to Las Vegas is 184 miles. 
If it took 14 hours to drive to your aunt's house, how long would it take to drive to Las Vegas?
~~~~~~~~~~~~~~~~~~~~~~~~~~


Assuming that the speed is the same in both trips, the time "t" under the question can be found from the proportion


{{{644/14}}} = {{{184/t}}}.       (*)


t = {{{(184*14)/644}}} = 4.


Notice that both sides in the proportion (*) represent the velocity.


Which is the same in both cases, according to the assumption.
