Question 339486
Since they are traveling in opposite directions
you can add their speeds to get their distance apart
given:
{{{25}}} = the speed of the southbound boat
{{{25 + 12 = 37}}} = the speed of the northbound boat
{{{d = r*t}}}
{{{124 = (25 + 37)*t}}}
{{{t = 124/62}}}
{{{t = 2}}}
They are 124 mi apart in 2 hrs
