Question 930508
Distance = rate x time


One bus
d = rt
d = 56t   {distance = rate x time}


Other bus
d = rt
d = 53t {distance = rate x time}


When traveling in opposite directions, their combined distances will equal 654.


56t + 53t = 654 {combined distances and set equal to 654}
109t = 654 {combined like terms}
t = 6 {divided each side by 109}


In 6 hours, they will be 654 miles apart
