Respuesta :
The rate that train 1 is going plus the distance:
35x+52.5
The rate that train 2 is going plus the distance:
56x+0
X=number of hours
Solve for X to find where the 2 trains have gone the same distance:
35x+52.5=56x
52.5=21x
2.5=x
The express train will overtake the local train 2 and a half hours after it leaves
