Question

Please help Thanky ou

Answer 1

Main concept: when they pass each other , each will have travelled the same time

distance covered by train A --- x
distance covered by train B --- 337.5 - x
time for A = x/55
time for B = (337.5-x)/35

x/55 = (337.5-x)/35
cross-multiply, solve for x, then find x/55
