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....???

they are travelling apart at a speed of \(80+90=170\) mph solve \(170\times t=425\)

dw:1377816734849:dw\[Distance=speed *time\]\[t=\frac{ D }{ s }=\frac{ 425 }{ 80+90 }=\frac{ 425 }{ 170 }\]
