REWARD AND MEDAL (:
1.) Two trains leave a station at the same time, heading in opposite directions. One train is raveling at 80 km/h, the other at 90 km/h. How long will it take for the trains to be 425 km apart? the teacher wants us to use r(t)=d using a 3 across 3 across below that chart. then do equation please....???

Best ResponseYou've already chosen the best response.0we have to solve these problems by a chart 3 boxes across below that 3 boxes.. Rate times time=distance rate for each train goes in two boxes going own.. time goes into two boxes going down and distance goes in two boxes going down...??

Best ResponseYou've already chosen the best response.0dw:1377816734849:dw\[Distance=speed *time\]\[t=\frac{ D }{ s }=\frac{ 425 }{ 80+90 }=\frac{ 425 }{ 170 }\]
