<PRE><B>Question 1157786</B>
&lt;br&gt;
Let d be the distance.&lt;br&gt;
Time at 60km/hr = d/60
Time at 55km/hr = d/55&lt;br&gt;
The time at 60km/hr is 10 minutes = 1/6 hour less than at 55km/hr:&lt;br&gt;
{{{d/60 = d/55-1/6}}}&lt;br&gt;
Multiply by the least common denominator, 660&lt;br&gt;
{{{11d = 12d-110}}}
{{{d = 110}}}&lt;br&gt;
ANSWER: The distance is 110km, or 110,000 meters.&lt;br&gt;
CHECK:
110km at 60km/hr = 110/60 = 11/6 hours = 1 hour 50 minutes
110km at 55km/hr = 110/55 = 2 hours&lt;br&gt;
