Из пункта A в пункт B выехал первый велосипедист. Одновременно с ним с такой же скоростью из B в A выехал второй велосипедист. Через некоторое время первый велосипедист увеличил

скорость на 10 км/ч. Если бы первый велосипедист сразу двигался с увеличенной скоростью, то его встреча со вторым велосипедистом состоялась бы на 3 ч раньше. Известно, что расстояние
между A и B равно 180 км, в момент изменения скорости первым
велосипедистом расстояние между ним и вторым велосипедистом
было меньше 70 км; на весь путь из A в B первый велосипедист
затратил 15 ч. Найдите первоначальную скорость велосипедистов.
