Question 1044865
.
Mr. Fisher travels from Boise, Idaho, toward Casper, Wyoming, at a rate of 56 mi/hr. Mr. Collins leaves Casper for Boise 
at the same time, traveling at 64 mi/hr. If the cities are 658 mi apart, how long will it be before the two men meet?

<pre>
  "How long" = {{{658/(56 + 64)}}} = {{{658/120}}} hours.


Bad numbers? - Really bad.


The two cars move toward each other with the relative speed 56 + 64 = 120 miles per hour or 2 miles per minute. Hence


  "How long" = {{{658/2}}} minutes = 329 minutes = 5 hours and 29 minutes.

Much better.
