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%2B35______300%28t%2B35%29
B______________________400_____________t______________400%2At

The table shows the expressions for times and distance. Solve first for t using highlight%28300%28t%2B35%29=400%2At%29.
