Ответ:

первая машина догонит вторую на расстоянии 159 км от города B, и это случится через 3 часа.

Пошаговое объяснение:

1) 87-53=34 км/ч - разница скоростей машин (на столько км за час сокращается между ними расстояние)

2) 102:34=3 ч - через столько времени первая машина догонит вторую

3) 53*3=159 км - на таком расстоянии от города В первая машина догонит вторую
