Question 1044434
Travel Rate Rule to relate rate, time, distance, RT=D

Forty-five minutes is  {{{(3/4)hour}}} and 48 minutes is  {{{(4/5)hour}}}.
<pre>
                   RATE         TIME       DISTANCE

REGULAR            r            t           d

SLOWER            r-k          t+h          d
</pre>


UNKNOWN VARIABLES:  r,d
(unit for r is kilometers per hour)
(unit for d is kilometers)

GIVEN VARIABLE ASSIGNMENTS:  {{{system(t=3/4,h=4/5,k=5)}}}


You would make some algebra steps to solve this system:
{{{system(rt=d,(r-k)(t+h)=d)}}}
