Question 959892

Two trains travel at 200 mph and 350 mph.

Let t,T be the time spent traveling by the slower and faster train, respectively, and let d,D be their distance traveled.

Suppose that both trains travel the same distance. Write an equation to determine how long the slower traveled traveled as a function of how long the faster train traveled
<pre>Distance for slower train: d = 200t
Distance for faster train: D = 350T
Since they traveled the same distance, then we can say that: 200t = 350T
{{{t = 350T/200}}}, or {{{t = 7T/4}}}, or {{{highlight_green(t = (7/4)T)}}}
