Question 1098830
Rate x Time = Distance,
In the one hour that Camilla left earlier she gained 50km on Harry.
{{{50*t+50=80*t}}}
Time is measure from when Harry left (7 AM),
{{{30t=50}}}
{{{t=5/3}}}
{{{t=1&2/3}}}{{{hr}}}
One hour is 60 minutes so {{{(2/3)(60)=40}}}
1 hour 40 minutes after Harry starts.
8:40 AM.
