Question 371920
Train A has a {{{12}}} minute head start or {{{12/60=1/5}}} hr head start.
In that time, Train A has traveled,
{{{D=80(1/5)=16}}}miles
The distance from the station for Train A is then,
{{{D[A]=16+80t}}}
The distance from the station for Train B is,
{{{D[B]=90t}}}
Find {{{t}}} when {{{D[A]=D[B]}}}
{{{16+80t=90t}}}
{{{10t=16}}}
{{{t=8/5}}} hrs
{{{t=(8/5)(60)=96}}} minutes
So {{{96}}} minutes from 11:37 pm would be 01:13am.
