Question 760971
Plane B begins travel when Plane A had already been traveling for 35 minutes.  The next quantity of time, t, is the amount of time that both planes were simultaneously traveling.  


Plane B moves faster and at some time 35+t for A and t for B, their distances traveled are equal.


Which Plane____________rate____________time___________distance
A______________________300____________{{{t+35}}}______{{{300(t+35)}}}
B______________________400_____________t______________{{{400*t}}}


The table shows the expressions for times and distance.  Solve first for t using {{{highlight(300(t+35)=400*t)}}}.
