We find what way passed the ice breaker for the second and third day: 90: 3 • 8 = 240 km. Now we will take for whole all way and we will find what share of a way needed to be passed to the ice breaker for the second and third day: we find all way which passed the ice breaker in three days: 240: 3 • 5 = 400 km. we find what way passed the ice breaker for the first and second day: 400: 5 • 2 = 160 km – in the first day; 240: 8 • 5 = 150 km – in the second day. Answer's . In the first day the ice breaker passed 160 km, in the second day – 150 km; in three days – 400 km
