Смотрите.
1) Обозначаем t — сколько времени они шли в первый день, тогда (t-1) — сколько во второй.
2) Теперь следующее соотношение — про 6 километров. Пускай в первый день они км, а во второй день — s2, тогда нам дано:
s1-s2=6.
3) Вспоминая, что расстояние=время*скорость (s=v*t), подставляем в эту формулу вместо s1 и s2:
(3,5*t)-(3*(t-1))=6.
Упрощаем:
3,5t-3t+3=6;
0,5t=3;
t=6.
ответ: Таким образом, в первый день они шли 6 часов. Во второй день — 6-1=5 (часов во второй день — 3*5 = 15 (км)

(4,25+6,57)-(4,49-2,57)-(3,51-1,75)=10,82-1,92-1,76=7,14
17,56+(9,28-5,56)-(7,01-4,72)=17,56+3,72-2,29=18,9
(14,7+0,053)-(9,7-2,31)-(1,01-0,047)=14,753-7,39-0,963=6,4
