Question 955895
<i>Two buses leave a station at the same time and travel in opposite directions. One bus travels k mi/h faster than the other. If the two buses are d mi
 apart after t hours, what is the rate of each bus?</i>


Basic Uniform Rates for Travel Rule, RT=D


Here the problem description is generalized using variables and the necessary equation may be identified and then formed.



___________________speed___________time____________distance
SLOWBUS_____________r_______________t______________rt
FASTBUS____________r+k______________t______________(r+k)t
