Question 402978
<font face="Times New Roman" size="+2">


Let *[tex \Large d] represent the distance traveled on the train.  Let *[tex \Large t] represent the amount of time spent on the train.  Then *[tex \Large 350\ -\ d] represents the distance travelled on the bus, and *[tex \Large 5.5\ -\ t] is the time spent on the bus.


Using Distance equals Rate times Time, we describe the train ride:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ d\ =\ 105t]


And the bus ride:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 350\ -\ d\ =\ 40(5.5\ -\ t)]


Substitute:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 350\ -\ 105t\ =\ 40(5.5\ -\ t)]


Solve for *[tex \Large t]
