Question 956604
_______________________speed_________time___________distance
First Part_____________60_____________(___)__________d-100
Baguio_________________30_____________(___)___________d
Total________________________________50/60


Uniform Travel Rates rule, RT=D for rate time distance.
{{{5/6}}} of an hour is 50 minutes.



_______________________speed_________time______________distance
First Part_____________60____________(d-100)/60__________d-100
Baguio_________________30_____________d/30________________d
Total________________________________5/6



The question is to find total driving distance.  Solve the total time
equation for d, the distance done in Baguio:
{{{highlight((d-100)/60+d/30=5/6)}}}


Compute {{{highlight(d+(d-100))}}} from that.
