Total time was 1 hour.


____________speed______________time_______________distance
Run_________6___________________d/6_________________d
Slower______4___________________d/4__________________d
Total___________________________1


The data show the equation formable, {{{highlight(d/6+d/4=1)}}};
you can compute any value using the variable, d, once you solved for d.
